If you want to keep the 67 transmission in the 67 truck, put the 67 bellhousing on the 350. The 72 bellhousing goes on the 292. Keep the flywheel and clutch on the engines they came on.

On both trucks pull the transmission off the bellhousing before you pull the engine, then pull the engine and bellhousing together. The heads of the bottom two transmission bolts are INSIDE the bellhousing. Swap bellhousings with the engines out of the truck, then install the engine and bellhousing together. Install the transmission after the engine is sitting on the mounts.

While the engines are out, get the right side (only) engine mount frame bracket off the 72 and install it in the rear set of holes on the 67 frame. The 67 right side bracket goes on the 72 frame in the front set of holes. The left side mounts are the same on both trucks, so you don't have to do anything to those.

The 292 intake manifold should have a port (with a plug in it) that you can connect the power brake hose to. You will need to plug the PB port on the 350 so you don't have a vacuum leak.
