Test fitting the Tremec TKX. I started with modifying a cross-member that I already owned. I had one cross-member from my '67 camaro and the original from the '68 firebird. I thought they would be the same, but they are not. Top is firebird and the bottom the camaro.
I ended up only using the cross-member from the camaro. I cut the center section and moved it back to align with the TKX mounting holes then welded it back together with some additional support material. I also added some spacers on each end to lift the transmission as I want it as tight as I can get to the top of the transmission tunnel.
I modified one side so that I can install the cross-member by simply lifting it into place and bolting it in with 3 bolts. If you ever tried installing a stock cross-member after subframe and transmission is in place then you know how much of a pain in the ass in can be to slide into position this mod make to super simple.
I created a trim ring around the hole for the shifter.
Then used my 3d printer to make a gasket holder around the shift boot. I used some 1/2" foam weatherstripping to seal the gap.
It tucks up nicely. I'm right at 3 degrees down.
