ls swap into my c10 finally

[sbc10guy]

Finally found a deal on a nice 5.7 ls1 backed with a t56 6 speed manual trans in a 2000 camaro. In the process of making the deal now but im going to go for it. I test drove the car today and he is going to pull the engine trans wiring clutch parts and whatever else I may need. He prefers to pull it himself which saves me a bit of work. He says he will label everything as he goes. Anything else I should have him save me off the car that will help me? And is there a good place to get most of my ls swap parts that I will need to install it into my 69 chevy shortbox.
