Question after converting a 7-1/4 to 8-3/4

..........As long as u have big bolt pattern 8.75 axles, not redrilled 1s.....ur small bolt backing plates r not the same..even if u drill the axles to big bolt...big bolt needs all big bolt components....kim.....

Here's a picture of what I won-the axles don't look like they've been redrilled (just figured the bigger holes are for access to axle retainer bolts), but I'll check them when they come in of course-thanks for the reply. I planned to keep it all SBP for the time being, anyway. Swapping over to BBP will require a little more money to do than I want right now. I already have a pretty good amount earmarked on one of Mark's Dashes, and that'll require a couple hundred more on gauges and such to get installed. I also have to get my exhaust worked this week, then drop in my "new" engine, then front glass....
