Do you mean a TH400 crossmember? If you have a 3-speed manual the only other factory crossmember was for the TH400. All the other trannys (4-spd, TH350, ST300) used the one you already have.
Is there an easy way to ID the factory crossmember? My '67 is originally a Sprint6 3 speed manual. I have a couple crossmembers that came with the car. I want to use a Pontiac 389/TH350 combo.
