Hey guys. I'm doing a 1992 4.3 tbi from an s10 (60k original miles) swap into my sas'd 1986 Toyota pickup. Have a 4" trail gear sas kit installed and no body lift. I have most of the parts and information. I've done lots of searching and can't find answers for a couple things still. I could really use some help.

1. Which exhaust manifold/headers will work? I prefer a stock manifold over after market headers because of the price. But I will do what ever is necessary. If modification is necessary for stock headers what does it require.

2. Which radiator are you guys using? I'd prefer to not cut into the stock core support. And which electric fan?

Thanks in advance.
Niko
