Need help w/backing plates

[bamafrost]

Need some help fellow enthusiasts...

I have a '68 C10 SWB (disc front/rear drum) that I am putting a '71 rear axle into to get the 5 lug pattern. Problem is the '71 rear has rusted out backing plates and I am having a !@%$&*# hard time finding ANYONE that sells repro ones. Tried the usual supects; Classic, Ecklers, LMC, POL etc. No luck.....aghhh.

Any idea if the '68 plates will interchange? I haven't got the '68 rear end here so I can't tell (those backing plates are like new). Seems as if they would fit knowing Chevy...but maybe not.

I know the dealership might be able to provide...just don't want to get "bent over the stump".

I am trying local wrecking yards also...no luck so far.

Any help/suggestions would be very appreciated. Thanks. Tom
