Will the TH400 cross member work on the 4 speed?

No, a P/G;3-spd;TH350 will be needed, the "straight" one. Also, there is a difference between a SBC & BBC. SBC trans mounting slots are in the center, side-to-side, BBC's are towards pass side approx 3/4(?) inch.

When installing x-member, be sure to install correctly, i.e., the three 3/8 inch holes for the OE shifter mount go to the driver side. This will also correct for the "tilt" of the trans mount.

Keep your TH400 x-member in storage.

You could fabricate one if you know somone with a welder. Start in the middle and work your way out
