Rear brake question?

[5258]

Will the backing plate on a 7 1/4 rear fit a 8 3/4 rear?

Thanks

The project I'm working on is relocating the springs and swapping out the 7 1/4 for a 8/34 in my 69 dart. I really didn't want to get into the brakes at this time and wanted to wrap up the rear swap first, I thought I saw a post in the past were someone said he had swapped rears and just kept his intire backing plate and drums in tact and just swapped it to the 8 3/4.

Maybe it was just wishfull thinking.

small bolt 7.25 backing plates only have 4 bolt holes...8.75 has 5...i just supplied my friend some 10" acking plates for a 7.25 cause the 8.75 were different

Doug 371,

Don't laugh to loud. Can that botton bolt hole be drilled out and if so will the 9in backing plate fit on the a body 8 3/4. Really don't want to swap out brakes unless its a last resort.

Thanks

i dont think the 4 bolts are exactly in the right place either...i had parts, so we didnt have to figure that out

Yes, I believe the four bolts are in the right place, but not 100% positive. Drill the bottom hole and see....

My current set up is 9in drums, My question is can I change out the rears w/o disconnecting the brakes, I really,really don't want to get into the brakes yet. Can I just remove the 7 1/4 axles pull them, leave the brake hard ware on the backing plate, drill the bottom hole in the 9in backing plate and then assy to the 8 3/4? Will it work?

Thanks

I believe it will, but you'll know for sure when you try it.

Thanks. Plan to do after stuffing myself with turkey Thursday, I'll keep everyone posted.
