[Diy_efi] Help, putting a 4.3 TBI on a buick 3.8L V6

[Charles Woock]

I'm game.  What vehicle/year would be a good donor?  The donor is critical. 
I can buy whole cars/trucks from an insurance salvage pool (through a 
friends dealer ID).  I'm going buy the whole thing and use as much off it as 
possible to save money.
