Yes, hold down brackets are required. They come up for sale once in a while on the various auction sites and i believe are being reproduced and sold aftermarket. Touch base with Don at Ohio Mustangs on this site, he will let you know what is available from his end.
As you are into originality and me being busy restoring with 71 CJ front parts atm. Got few small questions:
If you note, you will see the partial 429 label on my air cleaner... They did not come with this from the factory. This particular air cleaner lid is an exact repo from Semo Mustang Parts. I then refinished the original air cleaner lid, but without the label for "serious" showing....
1/ What kind of finish is on the twist locks brackets? Looks like yellowish vs the grey central latch mechanism. From what I saw beneath a layer of paint sprayed on original untouched parts, they had the same finish from factory. Were these offered in different finishes? Love the look of the locks brackets, very nice.
I don't believe there was a finish (at least of the colour variety, more natural look) on the hood lock brackets, mine were painted as close to a natural look as i could do to protect the metal long term... My engine bay was a disaster from year's of use and abuse so finding what was originally on certain parts was difficult. I did a lot of research to try and best determine what was best for my restoration. Everyone has an opinion and I don't put a lot of faith in MCA write up's. best to do your own research...
2/ Your hood latch mechanism seams to have the same color as the back of the grille. My grille also untouched in its juice has a more silver finish.
Did you spray both latch mechanism and grille in same color?
Again, I did this piece (as well as the hinges and the shock tower caps) with a special paint called ZincMate made by a company here in Canada called CRC. It contains a zinc coating to help prevent rust. I ordered the Matt Gray colour to best match the factory bare steel look. Again, I want long term protection and no rust...
3/ I see your grille has 2 brackets, mine has only one, but its having as you see on pict bellow, an angle, likely to reduce parts costs. 1 vs 2 always won in Ford's mind.
Not that I really care, just curious about the production date of your car. Very early 71?
I believe this has been discussed here before, my understanding is that early '71 build's had the two brackets and later builds went to the one bracket, costs savings for sure..... As a side note, the grille is off my very first Mustang I bought in 1979... I had a minor front end fender bender and went to the local Ford dealer and bought this grille for $106.00. When I scrapped the car, I took it off and put it in storage... As this will likely be my last restoration, I decided to pull it out of storage and put it on this car...
4/ final question, as I know you do factory restoration and me busy trying to restore/replate my bolts, I see the hood latch mechanism bolts are of the same alloy with zinc (with yellow passivation) as your fenders bolts. The original bolts on mine for the latch, are of the same alloy and grade as for instance the tower braces bolts, they have a white finish, not zinc. I wonder if there were different hardware used there.
These were put on initially as i waited for parts to arrive, I have since switched over to the colour bolts you note...
Very nice restoration btw!
Thanks! I follow your's, keep up the good work.
