Rear Backing Plates

[RustyRatRod]

I have some rear backing plates I am not going to use. How do I tell what they fit? They are the five hole plates so I know they at least will fit the 8 3/4 and Dana. Thank you drive through.

first picture is small bolt second is Big bolt , Notice the difference in the depth below the wheel cylinder for the axle flange. Big bolt is much deeper. If you post a picture I could tell you what you have. Last picture is front small bolt

Hope it is ok for me to jump in. Was just going to post a similar question about rear backing plates for my 72 Demon (8 3/4 with disc front). Are the small bolt plates the same for all years? I feel like I took A off of the car years ago but they had 2 1/4 shoes on them vs B which had the 1 3/4 shoes on them.

Thanks
