does stock 87-93 come with 7.5 or 8.8 rear ends ?

if i were to put in a posi diferantial, whats best, 31 or 28 splines and does it matter?

also, i was told to look @ the B303 Cam w/1.77 RR ... I've found the B303 Cam, but doesn't say it has the 1.77 RR[what is it?] ... is that a seperate part? or does it come with the B303?

and last question, is 3.08 gears stock? what's stock gears?

86 and up V-8 Mustangs have 8.8 inch rear-ends.

How much hp are you making? You may not need 31 spline axles, but they won't hurt

1.77RR's are are roller rockers that will increase the lift of a cam(stock it 1.6)

Stangs came with with 5-speeds came with 2.73's stock with optional 3.08's. Auto's had 3.08's stock, with optional 3.27's
