Poncho Mike, I'm searching for the HO setup. I've recently acquired a correct 72 HO for my 72 LeMans GT, so I'd like to make the install as correct as possible. Mine has the T-41 nose, so that's why I'm hunting for the full Ram Air HO setup.

Mr G, thanks for the heads up on the shorter throttle bracket. I'll take a look at that next.

Again, if anyone has a setup, or a partial set up. Really, any of the pieces that they are willing to sell, please let me know.

Thanks!

I also have a 1972 Lemans with the 455HO. Mine is a Lucy Blue 4-spd convertible. I've been collecting parts for years for that car. It may be going up for sale later this year.

At one point, somebody was maintaining a registry for 1971 - 1972 non-GTO 455HO A-bodies. I think there were only around 100 cars or so made over both years.

I may have an extra 455HO air cleaner, I'll have to check. I bought a repop top ram air pan a long time ago for my car, no spares on that part.

Good luck.
