Air intake manifold
I have 3 of them, all 318's, 73 Duster,86 Ramcharger,87 5th Avenue
problems you'll run into installing one.
Throttle brackets and kickdown rod can be solved by switching to a $15 AMazon Lokar knockoff cable setup,I bought 2 tansmission cables and used one as throttle cable.
port alignment and flow on 318 heads, a 30 minute port match em ,30 minute smooth out the intake manifold's runners and a 30 minute smooth out/stream line the valve guide bosses on the heads. It's worth it even on a stock rebuild.
AC pump bracket, you're going to have to fab one.
