383/Manual steering box/slant six stuff

I have a early 383 core motor. Its basically a long block(heads included) Its been outdoors for a loonnggg time. Well seasoned if you will. A unknown manual steering box (its MoPar just dont know what it came from). And a torn down slant six. Also a super six intake. What I need is LA rocker arms , shafts, pushrods, and valve covers. Also need exhaust manifolds for a LA. I also need a right hand(pass. side) upper control arm for a 72 drum brake duster. I need this stuff pretty quick so lemme know what you have. Im not looking for anything special just decent oe parts. Will post pictures this evening or tommorow.
