  1. As you know, this part is very hard to find. You've probably checked out EBay which has 3 listed. One excellent Repop for $750 and two originals for $1,250 and $1,500.
  2. I have a spare original Plenum and valves. Willing to let them go for a fair price. kcmash I sent a PM to kcmash.
  3. I'm looking for the under hood plenum that channels the ram air from the hood ducts to the breather system. Need the ducts as well, but the plenum is the main thing. The plenum and ducts are all the same for 71, 72, and 73. They're not engine or model specific, so any plenum from any 71-73 mustang will be fine. I know I can buy these from Dynacorn, etc. but looking for originals. If I can't get originals, Leon at Ford Ram Air (fordramair.com) has some really nice fiberglass replicas I'll use. Daily Driver stuff is fine. Thanks, Jeff J
  4. Can anyone tell me where to get a used OEM, or new aftermarket drive shaft for a 71 convertible 429SCJ C6 automatic. I think it would be the same one in the 429 Mach 1 with automatic tranny. Stock would probably work, but the engine is pepped up a bit (572 HP, 617 Ft-lbs on dyno). Thanks for any help. Jeff Jones, Louisville KY
  5. Hey Don C, thanks for the great reply. the CK Performance stuff looks great.
  6. Great. Thank you everyone for these suggestions. I'm definitely going to look into these two new options (Gear Vendors, 4R70W). I very much like the gear ratios of the 4R70W which are First: 2.84 :1 Second: 1.55 :1 Third: 1.00 :1 Overdrive: 0.70 :1 I don't think it was ever matched up to a 460 engine, hence the need for an adapter.
  7. Thanks for the great lead! Never heard of this option before. I read the web site up and down and all around. The Gear Vendors device is a really interesting concept and looks to be easy to install. Many advantages to this conversion!! But there's a distinct disadvantage that would still make me want to consider a E4OD or an AOD dedicated transmission: This system simply adds on to my old transmission. I still need to rebuild the old one, install all the high performance items, new torque converter, etc. So the final cost will be about $2.5K for the rebuild plus $3K for the Gear Vend
  8. Hi Everyone! - The quick question: What type of automatic overdrive transmission can I install in a 71 mustang with a 429 engine? ::thumb:: The details: It's a 71 convertible. I'm replacing the original 6 cylinder / C4 tranny / 8" 28 spline rear with ------> 429 SCJ (dyno shows 572 HP at 5000 rpm and 617 Ft-lbs at 4600 rpm) / 9" 31 spline rear with N-case, Trac-Lok, with any choice of gear ratio, and the choice of transmission still up in the air. :chin: The quandary: No luck by looking at previous threads. I have all the "stuff" to make the switch, but haven't decided yet
