I need some help with an old Dodge truck.

Thanks.

Two items I am having trouble finding on line is a new intake and a new exhaust manifolds. These ones are cracked bad. Someone has already ground on them and tried welding them so there is not a lot of room for error left and my cast iron welding skill is not the best....

Any one got a source for old dodge truck parts?

DMC is where i have been looking.
Facebook has a page for these trucks, parts are out there.
I might be V-8 my truck, but need the numbers to see if the manifold will fit. Plus I have an extra flat head with manifolds.
