Steve, my 1995 K1500 Cowboy Cadillac.

You have no idea how glad I am to find this thread. I've got a 94 rcsb c1500 that I've been debating on engine swap options. My dad has a friend that put a 500 Cadillac in a gmt400 back in the early 2000s and I'm thinking all that torque would make for a really fun street truck. Your thread will be invaluable once I get started

I'm still digesting up to page 12, my interest in the steering gear conversion- contacted Borgeson about a simple adapter- they do make one.

We do have an adapter that will slide on the 17MM DD input shaft and convert it to a ¾”-30 spline. You will need to grind a flat on it to match the flat cast into the factory steering shaft. This piece does not have a distributed part number so you will need to give us a call to order, cost is $47.50, you can reach me at 860-482-8283 to order.

What a read. Nice bit of work you've done there. Really takes me back to my Eldo days. 73 drop top, white on red. Not much of a truck but sure was a boat.

So- received the adapter from Borgeson which you have to file a flat to match old splined input shaft. This should open up options for 88-98 trucks to 2007+ sometime later they switched from a 32 spline to a 33 spline output shaft.

I wish I had known about that adapter at the time. That would have made the swap easier. I may actually look into getting one because I have never found a good solution to make the boot at the firewall fully tight.

The Delphi box- is it just an evolution or a cheaper quality box?

It is an evolution. The valving was based on contemporary rack and pinion style setups. The Saginaw is an early 60's design. The Delphi has much better feel.

I have upgraded to GMT900 brakes! These are the biggest that fit with a 17" wheel. Since I was already running GMT800 brakes, it was a snap to install. Only took about an hour. I need to bleed them a bit more but with the ALDL trick to cycle the ABS pump I should be able to get the trapped air out of the system completely.

How big are those rotors? Were all 6 lug GMT900 brakes the same size?

 

[MIHELA]

13 inch rotors. They also use a much nicer PBR caliper with larger pistons. As far as I know the GMT900s all use the same front rotor, these came off a junkyard 2008 Yukon XL.
