Frame question

[phat46]

Does anyone know if a frame from a four door '68 Chevelle is the same as the two door frame? What other G.M frames are the same as the Chevelle? My brother had a '68 SS 396 given to him that needs a frame and he has access to a four door  frame but we don't know if it'll fit. TIA

In 68, no it's not the same. any GM intermediate two door, Chevelle, Lemans/Tempest, Cutlass, or Skylark, as long as it has the same number of door will fit. Also 68 to 72 should fit, thought there might be small differences.

The two-door frame is 112" while the four-door is 115"

I have shortened the four-door to 112" for oval-track race car purposes, but never for a street application.

I would guess that you can take three inches out somewhere and make it work - probably at the rear torque box. If it is a particularly good frame, I would probably try to use it.

Careful measuring and re-measuring should answer any questions.

I recently read that someone is re-producing these frames now, but, as you might guess, if you need to ask the price, you probably can't afford it.
