The 64-72 Chevelle crossmember fits these cars very nicely(I've done this) after trimmimg a little length (less than an inch) off each end and redrilling the mounting holes. Bolt it up to the tranny mount then and square it up to see where you need to drill the new holes in the frame. This crossmember has two humps for dual pipes, and I believe the 73-74 Chevelle/Monte Carlo member could also be made to easily fit.
