Slant Six Conversion Project

I have officially recieved my 360, via a 1975 d200. I also recieved my new Carb, a Holley Street Avenger 670. Hopefully I will be able to pick up my intake manifold tonight.

I have a few questions

1) Motor Mounts - I have heard a truck mount can be used for the one side and the slant mount is able to be used on the other. can anyone confirm or deny this? What years of truck is the mount supossed to be from?

2) Exhaust Manifolds - Can i use the exhaust manifolds from the truck, or am I going to need something else?

3) Center Link - The car was originally a 273 car that was changed at some point to a slant six. How would I be able to tell what centerlink I have? Would the person who switched to a slant have had to switch to a slant center link?
