Considering LS1 motor in 1st gen Camaro...mounting??

[BuddyP]

I'm pretty sure I want to do a LS1 with a 6 speed with my '68 camaro project. What mounting hardware/issues should I be looking out for.

Mainly want know what I need (and who to get it from) for tranny adaptor crossmember (or can I use stock crossmember?) and motor mounts/mounting. The less $$$ I have to spend the better for my budget, but at the same time I will spend more to do it right the first time around.

What are some of the other things like gas tank, fuel pump, radiators, misc, ect.? Just want to be able to keep my eye out for some of this stuff in case I find something nice and used for sale somewhere.

Thanks
