Another Chebby disc question

[TOOLMAN]

Does anyone know if you can use the backing plates from a 3/4 ton Chebby truck. I've read that you can and I've also read that you can't. Does anyone know for sure? I'm starting to put mine back together and the inner pad doesn't seem to fit at all and outer seems as if it is not going to make complete contact. It appears that the 3/4 ton backing plate may be too large.

Any advice would be great.

Let me know if you want pictures of mine, I can disassemble and take some after work today for you.

Thanks for the offer G's. Just for everyone's information out there, I utilized backing plates from a '78 1/2 ton and they work just fine. Cost me $16 bucks for the pair at the junkyard. The spindles from a '78 won't work but the backing plates are the same as the earlier years.

There are 2 styles of backing plates the older ones are all complete cast steel others are just arms to hold the caliper with a tin plate for the dust cover .. Both work But the complete steel ones might be a little stronger

The 71 chevy I just pulled mine off of had one of each. I figured the complete circle steel one was from a later one because there were hammer marks on the spindle (doh!) from some clown working on it before. I'll have to file off some of the displaced metal that was shifting the inner bearing out on the spindle 1/16".
