ok so my 3.91 diff on my 325 shit the bed last night, with two shattered spider gears.

now im impatient and do have a small case 4.27 diff sitting in my garage, and im thinking about swapping the flanges over(straight swap?) and just sticking this on until another proper ratio one comes up.

is this a silly idea?

Medium case diffs have thin flanges and small case one's have thick flanges...

Your 4.27 will fit,will render first gear redundant and perhaps second as well!

Do not consider it a permenant fix,though,the bigger engines eat small diffs as a mid-morning snack.

ah havin looked quickly earlier i thouht they ran different size driveshafts, which i now actually looked properly and they dont. Im going to try wait a few days see if any diffs come up, as always when you need something some people want top money for stuff ive not even been able to give away in the past lol.

cheers
