8 1/4 Differential desperately wanted

I dont understand why it should hold up your project. Depending on the plans, if its brakes holding you up, some 7.25’s and 8.25’s share the same brake cylinders,shoes and drums.

i got what i thought was an 8.25 from a diplomat, a tad wider but would suit my need. 10 bolt cover. But it is a 7.25. The tell tale is the step in the axle tube, 2-1/2” at diff housing stepped up to 3”.
8.25 is 3” right through. When looking for a diff, dont forget to ask for shock mounts too.

things i learned in the last few weeks, diffs with very high ratios, 2.26 in my case, will not take a low gear set. The carrier is different.

I wouldnt think twice about running a 7.25 if thats all i had,they just cant handle big power.
