Best donor vehicle? I've read this and other threads and I'm clear on most of the details of this swap (great info BTW). But I'm not clear which vehicle would be the best donor. Obviously a 5sp w59, but does it matter if it's 2WD or 4WD (I see inputs into the ECU for 4WD, 4L, and t-case neutral)? Is this an issue for California SMOG or performance? I've read about the 1st, 2nd, & 3rd gen wiring differences and the T100 oil pan, but are there other issues that would make one donor more or less desirable than another? A summary of the pros and cons would be helpful. The target vehicle is an 86 Xtra cab SR5 4WD w/22R-E EFI & W56.
Thanks
