Aftermarket Crossmember Fitment for 79 LeSabre

[McRockin]

I would like to run headers off the sbo i have currently installed. The crossmember is not notched or have a hump so i can run exhaust. I also want to know if these crossmembers are the same as a g-body car or something, im lokoing for one that will fit. What are my compatibilities? I have a TH350 behind the engine.

Different chasis all together. LeSabre is wider. No.

A crossmember out of a 94 to 96 Caprice/Fleetwood/Impala/Roadmaster should fit, and is humped for a dual exhaust, but might not work with a TH350. An old early 70's A body crossmember might be wide enough.
