Brake conversation question

No directions ? online maybe ?
Negatives outweigh the positives on a rear disc brake conversion.
Just read the posts from everyone who has done it.
The vast majority of the time they either can't get a decent pedal or no pedal at all.
The rear disc brakes do only about 20% of the braking.
Stick with the drums and just use better quality shoes and drums for added braking efficiency.
Flush the rake system with a sealed bottle of brake fluid.
Never use a container that has been uncapped for any period of time.

LOL!

The negatives outweigh the positives? Not even close. Rear disk conversions improve both stopping distance and brake feel.

The problem is that people use cheap kits, don't consider the changes they're making in the hydraulic ratio between the MC and the caliper piston size and how that changes F/R bias, and use calipers they're not familiar with. Every rear disk brake conversion I've seen go wrong was improper installation or adjustment (or a faulty part that needed to be replaced).

Learn how to do the installation properly, and become familiar with the calipers that you're installing and the procedures needed to adjust them properly and rear disks will outperform the factory drums all day long.

So the OP mentioned a 7 1/4 vs 8 3/4. If the 7 1/4 is SBP then the short answer is no. Housing flange to axle flange on A body ALL up to 72 was 2.38 inch. Not sure if the number is exactly right so don’t hang me out to dry. BBP ALL were 2.5 inch housing flange to axle flange. Those kits are sold like that and available because with a couple hole relocations they will bolt on fords and AMC. Both used the same wheel bearing size as Mopar.

This. If it's a BBP 7.25 the kit will work. If it's a SBP 7.25 it probably won't.
