Help with 14 bolt disc conversion

After having the parts do to my 14 bolt rear disc brake conversion in the box for over a year I decided to do the swap last night. I bought the kit from Off Road Unlimited and downloaded the instructions before I started.

Everything was going easy and I couldn't figure out why I had waited so long to do the conversion (should've knocked on wood). I tried to put the caliper on and it wasn't opened up wide enough so I messed around with it for some time before I decided that they must've send me the wrong spacers because even if I could get the caliper with the pads over the rotor it wouldn't line up with the bracket.

I went back into the house a little disappointed to say the least, then I thought about it some more and decided to try the other caliper. Guess what??? It fit perfectly so they sent me the wrong caliper for one side.

The caliper that works is a delco moraine with a number of 6473499 casted into it. I've tried looking that number up online and can't find it. So does anyone know what caliper I need for the other side or what make of vehicle ORU uses the calipers from? I'll just go and buy another one if I can figure this out so I can get my swap complete.

Any help is greatly appreciated,

Bill

It comes off a Cadillac Eldorado's 1976-1978 it has the E brake.
If you don't want the E brake you can use the same calipers off a 3/4 ton 8 lug front axle they will work but it will not have the E brake. Only the Eldorado's Calipers have an E brake hook up.

No e-brake, I'll try those, thanks for the help.

Re: Help with 14 bolt disc conversion

I just got back from the auto parts store and installed the caliper from a 82 3/4 ton. Everything looked good until I went to install the new brake lines. The diameter of the whole on the caliper I just got is smaller than the one on the caliper that came from ORU so I guess I'm stuck until Monday when ORU's customer service is open.
