Frame 70 Wildcat (LeSabre?)

I'm working on restoring a 70 Wildcat Conv.
Does anyone know what frames are the same (other than the Wildcat) and years? Wonder if the 2-door hardtop has heavy duty frame too.

For a 1970 Wildcat I'd use an AMT 1970 Impala frame. It's not the most detailed, but as far as I've know it's the only full size post-1967 GM kit available. I'm sure it would work.

Now, what you'll do about the interior is what interests me.

Thx Layla's Keeper! Sounds like you know your cars. I'll pass this on to my brother. The interior is in pretty nice shape, but you're right. It's custom Wildcat. Need a donor car, I think. Too late to buy one already done. That's no fun anyway.
