Full detail frame for 75 Cutlass

[thatz4u]

what are the options??

[Snake45]

Wheelbase is the same as '70 Monte Carlo and '68 El Camino, but I don't know if the A-body frame is the same for the Colonnade years.

Thats 4" too short. And again, I'm not even sure the frame is the same between '64-'72 A-bodies and the later cars.

The biggest visible differences between the 1968-72 & 1973-77 GM A-body frames is gonna be the shapes of the front suspension control arms and that the frame horns on both ends of the newer car are enlarged for the bumper impact absorbers. I can go look to be sure but am thinking that the 1973-77 frames don't have that little skid plate under the first crossmember as on the AMT 1969 442.

Also, dual exhaust was dead starting in 1975 so you'll need a single hump transmission crossmember.

Fun fact: after the 1977 A & G bodies ended production that same frame then went under the RWD 1977-96 B & C bodies (Impala, LeSabre, Delta 88, Cadillac Brougham, etc)

Best option might be the Revell 1992-93 Caprice. It will have the right frame, suspension, floor pans. And it should have the correct tranny crossmember & exhaust system.. Dual exhaust made a comeback in 1994 so next best may be the Revell 1995? Impala SS. It will look right except for the dual exhaust crossmember & pipes.

You might try one of these.

The Revell 1977 Monte has a vague Palmer-type chassis with glasspack mufflers.. Better to use the Jo-Han chassis if those are your only choices. My humble opinion.

After due consideration, i'm pretty sure the 1990s Revell Caprice/Impala SS kits will have the small Cat Convertors which would be wrong for 1975. I have a complete 1992 B-Body sitting here and i can look at the convertor if need be. But you might need to cut in an older convertor.

I wonder how far off the chassis from the Revell '83 Olds Cutlass would be? I have both. So, I may have to check that out.

Here's a photo of the '83 Olds chassis under the '75. Just giving it quick look over, it looks like the wheelbase is off by 2-3 mms comparing the bodies. One could easily stretch the frame by cutting just behind the spring pockets and adding the needed amount. Might be able to use the underhood detail from the '83 also.

There are some later El-Camino kits that may be close, as well. Both 1/25 and 1/24, so one should fit.

The Collonade Cutlass cars had a 112 inch wheelbase, same as the 68-72 Cutlass. If you want similar (but not exact) frame and suspension, use a 72 Cutlass. It will work with trimming and the suspension details are mostly correct. The sway bars mounted differently on the earlier cars but at first glance the suspension looked the same Floor pans are different but mot folks would not know that unless they owned the real thing.

I used the 69 chassis in a few collonade cars. It was the closest chassis at the time and it fits the Johan Cutlass body perfectly!

Like the Doc said, I didn't know enough of the details to make a difference. Looked good to me.

[Repstock]

You didn't ask this, but if you're trying to make the underside reasonably detailed and correct, you might want to do the same for that '75 front end. It's not very close.
