thank you

You will be able to use the same bellhousing but I would upgrade the clutck to an 11 inch if it isn't already. You can use the same engine mount frame brackets just get motor mounts for truck small block V8 (63-'72) Probably the best bet for headers will be the ones for that year of truck. Some of the newer ones will work but they can be a little tricky to fit around the clutch bellcrank. It kind of depends on your intended useage of the truck. The ones for that year of truck are small tube and far from equal length tubes. The headers for a newer truck can be had in a larger tube diameter and closer to equal length tubes. I can dig up some part numbers for the newer ones if you want to give them a try.

As for the parts you are looking for, take a look in the classifieds here on the board and also check out the board vendors that sell those type of parts. Sometimes new parts are the best way to go.
