    Right now I have true dual exhaust running down the passenger side until it gets passed the crossmember and the drivers pipe runs over to the drivers side.

    When I install headers on this creature this winter I want to run them straight back and don't want to modify the current cross member. Do they make an aftermarket one anywhere or do the make a universal one that has to be welded up?

    Unfortunately no one makes an after market crossmember for the 77-90 models, but i posted a topic in the "After Market Parts/ Upgrades" thread about the tranny crossmember. I also installed dual exhaust with headers, but i modified the original crossmember, you can find that in the "Projects" thread.
