[68 IRON]

When it comes to ps brackets, should I grab the brackets and pump as a unit?
Just wondering if its worth taking a pump not knowing if it even works but on the other hand the setup has about 5 parts (brackets) that make up the assembly. This is coming out of a parts yard, 79 Nova, non integrated head (lots of sense lines to the intake) HEI (got it), and its hooked up to an auto tranny ( might get the cables and such for the kickdown). I when all else fails,
just rob everything I can and figure it out later? Let me know...I new to the whats gold and whats common parts hunting.
