There was more time spent in the garage today. The release fork location was determined and the hole was laid out. A 3/8" hole was drilled in each corner of the opening. I'll need to get a saw to connect the "dots".1203111254.thumb.jpg.1e35ed78459966a9bf933710a64557ce.jpg The fork and bellhousing boot are from LMC truck for a late 60's GMC truck. 1203111221.thumb.jpg.203ea910b429d216ca5d6292186558ed.jpg 1203111132.thumb.jpg.c6c649b5d475ac34303b21d3e46e0b51.jpgThe pivot from the 3.8 bellhousing is going to work with the new fork after some slight modification to provide clearance for the fork retaining clip. 1203111236.thumb.jpg.965f5cbd3847f1ae33a914f9fa375c9d.jpgSince a tool run is necessary I moved on to determining the size and shape for the frame and bellhousing brackets for the equalizer bar. The templates will be transferred to some 1/8" flat stock and welded together. 1203111702a.thumb.jpg.3dac5f64000614e4023bcdf668098d83.jpg 1203111702c.thumb.jpg.fd18196143196e5c80245dbdade2fa40.jpg At this point the position of the equalizer bar has been determined from there the levers and rods can be mapped out. Enjoy the pictures. I just hope the masking tape holds! LOL

I don't think it will be an issue the trans is rated at 300 ft/lb and my Cleveland is a very mild piece. The car is a driver and I will not be racing it. There are many parts available to upgrade the strength if it fails. They used virtually the same trans behind the Cobras IIRC that was rated @ 330 ft/lb.

 

Famous last words... "It SHOULD be OK" LOL!

SO THE 3.8 BELL HOUSING WILL BOLT TO THE 351 I ALSO WANT MINE TO GO FROM AUTO TO STRAIGHT DRIVE AND JUST WANT TO BE SHORE BEFORE I START GATHERING PARTS

Yes the 3.8 bell is bolt on. The release lever exits very low (see the photos, rectangle hole) so I am cutting a new access hole. The 3.8 bell also uses a 164 tooth flywheel which allows use of the '73 11" clutch. The only thing is you need to run the '94 - '95 Mustang transmission which has a longer input shaft than other t-5s. My plan is to include a complete parts list, prices, vendors and dimensions of custom parts at the project's conclusion.

Some small progress today. I finished tacking the clutch pedal bushings in place and started cutting metal for the brackets to mount the equalizer bar. No pics of today's progress, nothing really changed appearance-wise.

Ken PM'd a good question concerning my parts selection so I copied it here because we thought it was good information.

HI Jeff

 

The need for the T-5 with the longer input shaft is because of the bell you're using right? I was told that since mine is a stick already that I had to use earlier T-5 as it will bolt up to my bell but then I need to shorten my drive shaft.

 

Ken

 

Hi Ken,

 

That's a good question. I actually chose to look for the longer input trans since it will also move the shifter back about 3/4" and more centered in the stock hole in the floor. Since I'm kinda tall at 6'3 I felt that would be an advantage. The 3.8 bellhousing is about 1/4 the price of a 5.0 bellhousing so that was a no brainer. The unexpected benefit was the ability to use the c-6 crossmember ande trans mount.

 

As far as the driveshaft goes, I'll cross that when I have to. If the C-6 sells I'll be putting an Explorer 8.8" in along with a cut down Ranger aluminum driveshaft this winter as well.

 

So to sum it up the trans drove the bellhousing decision.

 

If you have any other questions please ask. That's why I am doing the thread. If you don't mind I'd like to add this to the thread.

Good info Jeff. If you need any help or have any questions with the explorer 8.8 let me know, thats what i am running in mine. Worked really nice with little modification. Nice to have disc brakes all the way around and posi 3.73's. The tranny you used, is it only availiable in the 94 95 mustangs with 3.8 or did it come in the 96 and up also?

The trans is from a '95 5.0 GT. The bellhousing is from a 94 to 98 3.8.

 

On the 8.8 did you modify the Explorer rear to center the pinion?

No i didnt center it up. its only slightly longer on one side. u joint seems to handle it ok. im running around 400 hp and no troubles yet. no vibration or anything. Ihave had it up to about 110 120mph. then let off. scary that fast! The rear has held up through 2 sets of tires getting burned off :D

 

71badmach... mine was an8 inch with 3.00 open gears. The 8.8 is 3.73 posi with disc brakes. So I killed a few birds with one stone.

My car has a 9" and I want to go to the 8.8 because it is a more efficient design. The 9" is very strong but it also uses a lot of power to turn it.

  • 1 month later...

Explorer 8.8 is also 31 spline, most were limited slip, and 95 and later were disk brake.

 

EXACTLY!!!


Good info, thanks!

 

Great thread that I missed while I was on sabbatical. Thanks for pointing it out in a recent post Droptop!

 

My 302 FMX Mach 1 is getting this treatment as soon as the Q-code is on it's feet.

 

I think this is going to be the best modification yet.

73, let me know if you prefer we not "dirty up your thread" with other stuff, but I did some research on the 8.8 and found this site:

http://www.therangerstation.com/tech_library/Explorer8_8.html

 

It is geared (pun intended) towards off road, but still very informative regarding the 8.8 rear end.

 

I figured when I do the swap the 2.73 ratio has to go, the 8.8 for about $400 would be the way to go.

All these discussions are good. We may as well talk tech since I have a kitchen to finish and it's too cold in the garage anyways. An 8.8 swap is next on the agenda.

 

There is some good 8.8 modification info on this thread on a tri 5 site.

Post #4 is particularly good.

Dumb question but what is the stock width of a 9 inch in our cars vs the 8.8? Would the offset mods be necessary in our cars?

explorer 8.8 is 59.5 wms-wms. Be aware that you are also competing with Jeep guys for them, so that is why the prices are sometimes higher. They got for $136 at my local pull it yourself yard.

I have an 8.8 in my mach 1 for about 3 years now or so and havent had any issues at all with it. I left the offset alone and had my driveshaft modified to fit the length. The only thing i did was weld the axle tubes to the housing for strength. Also tube diameter is different then our 9 inch. I had the driveshaft shop that modified my driveshaft make me up some new u bolts and i cut my shock mount/spring plates up and weled up some new ones to fit the new diameter axle tubes and drilled new holes. The spring perches i bought from summit and welded them on. Overall pretty easy install. For the parking brake, i took the drum brakes apart on the 9 inch and took out the little arm that the parking brake attaches to and cut it off and welded it to the parking brake arm on the new 8.8. Now your stock cable will work and you have a working parking brake. let me know if you have any other questions i might be able to answer some of them. Everyone will go about it differently but thats how i did it. Good luck. Kevin

From what I've read the overall length of the Explorer rear is 2" shorter than on the 71-73 Mustang.

I read this thread http://www.7173mustangs.com/thread-9-inch-width--3833?highlight=9+inch and BT said that it is 56 inches from flange to flange and I mistook this measurement for the wms-wms. :dodgy:

 

My bad.
