Double Hump Crossover
I was wondering if anyone knows the answer to my question of was a double hump crossover offered in my 74 Omega? It was in there when I bough the car. seemed to be original but the transmission is sitting a little high on the back side, (not as level as I think it should be). I don't think duel exhaust was offered so I see no reason a double hump would be there from the factory.
Thanks for any info.
BTW is a 350/350

Since an Omega is basically a Nova in drag, and 68-74 Novas DID have dual exhaust option, stands to reason the same crossmember is used in Nova, Apollo, Ventura and Omega.
I can't visualize GM having separate part numbers for single/dual exhaust applications on the X car when the A-B-C-E cars all used the same crossmember for both dual and single exhaust cars thru 1974.

Dave, I'm pretty sure all the X-body cars used the same double-hump trans crossmember right through 1979. The subframe did get some changes in 75 to accomodate the new front-steer arrangement, but it was mostly unchanged from it's original version dating back to the 67 Camaro/Firebird and adapted to the Nova in 68.
