Cutlass Frame Questions

grt05 · March 18th, 2009, 11:18 AM

Hi All,

I'm new to this forum and I have a question about my '69 Hurst/Olds. What year frames will be a direct replacement? I've read '67 to '72 A-body frames will work, but should I really just search for a '69 Cutlass? Any help would be appreciated.

Thanks,

Mike

All 1968-1972 A-body 2dr HT or sport coupe (post car) frames will interchange. That means Chevelle, LeMans, and Skylark in addition to Cutlass. The 69-72 Grand Prix and 70-72 Monte Carlo are also A-body cars but these two use a unique frame with a different wheelbase. The 64-67 cars use a slightly narrower frame with a longer wheelbase (115" vs. 112").

Thanks for the reply. Excuse me if my questions seem ignorant, but I am new to this. Doesn't small/big block make a difference? Would there be small differences between the models such as mounting holes or tabs or something like that?

Thanks

They'll interchange, however, I'm fairly sure the '68 frame is a one-year only frame. Think it's different for '69. It fits, but they're different. At least this is what I was told when I discovered mine was full of holes and cracked.

The frame for BB/SM doesn't matter. However, Olds used different engine mounts for BB or SB.

68-72 will all interchange. All A-body frames are drilled for all the different divisions motor mounts. All 68-72 A-body frames have both sets of crossmember holes pre-drilled.

Once again ONLY for 1969-1972 and either BBO or SBO brackets can be used with either BBO or SBO, so long as the matching rubber motor mounts are also used. In any case, they bolt to the same bolt holes in the frame.

Welcome Mike.
There are a few of us with 69 H/O's on the forum. Post pics when you can.

On a '68 frame the pass through hole for the rear brake flex line is almost in the centre of the crossmember and on '69 the hole was moved 10 or 12 inches outboard...

Thanks for all your replies. Now I can start looking for a new frame. Once I get the car out of storage I'll post some pics.
