LS into a 72 GMC

[greentruck]

Pretty cool that four of us are doing the same swap. I'm using an ls6/4l80e/np205. To mate the 4l80e to the np205 I used this advanced adapters kit

It's a tail shaft swap. What diff gears to you plan on using? What are you other guys using? Do you plan on using lockers?
Right now I'm ready for re assembly. I'm stuck on what headers to use. Can't seem to get a definite answer of what works and what doesn't. I know trail blazer manifolds fit but would rather go with headers. Ive "heard" that Schoenfelds fit but can't confirm nor can they. They're going to ship me a set to try and pay shipping back if they don't. Suburban99 what headers are you using?
