180sx diff question

[joey]

im going putting a different diff into the car and the diff i got the 2 front mounthings are the large holes but the one in the car now has the small holes.
do ye buy the bushing and bolts off nissan or what do ye use?

You should get 2 big bushings with the diff. I had a diff with 2 small holes and I put a diff with big holes + bushings, straight fit.
Just double check if the diffs are of the same length, they vary between abs (longer snout) and non abs (short snout)
