I got a couple leads from friends and can get a complete harness for $470. MUCH better.. Now, I guess the MPFI is back on the table. To go TBI I'd have to pick up a $300 Edelbrock intake manifold and adapt it to a TBI unit. And then buy a harness and reflash the computer lol. Ever feel like a ping pong ball???
The suspension arms I'm using are essentially recycled from a 80 series Land Cruiser. The suspension bolt diameter is 18mm. The frame side of the radius arm is going to pass through the frame and then through the suspension link. This makes the bolt significantly longer than is readily available. Finding a 18mm bolt that is about 170mm (6.69") long is not easy, and they cost quite a bit individually.
I can drill the suspension bushings out to 3/4" (19mm) and get a 6.5 or 7" long, grade 8 bolt a lot easier, but it'll add another step when I replace the bushings.
Course, finding a 18mm sleeve for the frame may make this all a moot point..
Gotta go look to see if I can rent a magnetic drill press to drill the draw for the frame side suspension. I think united rentals or sheen has them. I don’t trust myself in making the sleeve straight for some reason.
