Installing a Delco SI in an R1 Avanti
I got an email today asking me where I got the bracket to install the GM alternator on my R1 Avanti. I figure I might as well post the info here for all to benefit.
The install was simple, I used a standard one wire GM alternator, it gets mounted upside down (the alternator wont care). I had to redrill two holes, the R1 bracket is two pieces. I unbolted the 3 bolts that hold the small bracket to the large bracket, and moved the bracket to the front. Basically the front hole becomes the rear hole. Than I drilled two holes the same size as the others and remounted the small bracket in the forward pattern. I dont recall having to bend the arm on the bottom, but the pulley should live up fine in this location.
