Anyone know of a manufacture of a crossmember to bolt up a 700r4 in a 68 camaro? Thanks

I used my origional crossmember. I had to put the front bolt hole in the cross in the rear hole on the frame. I drilled new rear holes in the frame.

On my 69, I used my TH350 crossmember, my mechanic altered it to fit and give access to the rear pan bolts but it worked.

I got mine from them (I think)...works fine and looks nice.

Try Detroit Speed and Engineering or Street and Performance (Mena, Arkansas).

Seems like i've seen hotchkis offering one as well?
