I have an adjustable fan controller that I used for a few months but swapped in a LT1 and use the PCM now. There is plenty on the leads to be reused. It will control two fans and comes with a little bracket I made. I have two sets of gears, both GM 3.23's. One set is a 7.6 and the other is a 7.5 set. Both in good shape. I also have a set of Percy's aluminum LT1 header gaskets. I used them for 5 minutes then pulled the motor due to a knock. I found they did not seal the tubes on my Dyno Don headers.

Fan controller $25 shipped

GM 3.23 gears 7.6: $50 shipped

GM 3.23 gears, 7.5: $45 shipped

LT1 header gaskets: $25 shipped

All shipping is to the lower 48. If you live outside the lower 48 you will pay a little extra for shipping.

 

Series 2 or 3 on the gears?

NM. I fail!
