Can I run my 4.5" shackles or will I need 6"?
I'm not sure if you will have the right angle on the shackle with your 4.5er. I have a 6" shackle.

I will look into it. The more I look at the blazer from the side the goofier it looks with the rear end too far forward.I'm not sure if you will have the right angle on the shackle with your 4.5er. I have a 6" shackle.
Its a modified transgo kit put together by Dana at probuilt automatics, it is his HD 4x4 kit.What shift kit do you have?
I was expecting it to because my 700 used to as well. But then again the 700 didn't care of you were in 4LO either.Maybe it's a 4L60 thing. My 700 will, quick. lol

You have to tap into the compressor clutch circuit pre cycling switch. Then you'll have constant 12v anytime the a.c. is on.This is exactly what I was pondering over the other day. Not sure how I'm going to work my Vintage Air type set up with the ECM. I has to turn the fan on with the AC switch, not the signal to the AC compressor clutch. Don't want the fan to cycle on and off with the clutch.![]()

Lol are the springs hard to drill thru? I imagine it would be some pretty hard material...To get the tire centered in the wheel opening without gaining lift...I drilled a second hole in the spring perch one inch forward. Easy-peasy, cheap and cheerful. Just did mine this weekend. 3/4" is probably perfect, but one inch there is a bit more meat between the holes....hmmm, that sounded dirty.
Anyways. Easy fix.
Oh! I see now.... duh [emoji53]Not the springs, the perch itself that is on the axle.

Will do, I got it figgered out [emoji41]Share your wiring schematic when you are all done. I was wondering the same thing since I plan to get the same setup you and Teck are using for AC. Getting the wiring setup right so that the fan cycles on is not exactly super simple.
