r31 rear disc setup could probably be adapted if none of the many other cars fitted with a bw68 had discs

has any one done a disc brake conversion on a 120y diff also im planing on removing the leave spring and making a 4 link rear for it has any one done this also

if you do nothing yourself, will be around $110 an axel to be cut down
and another few hundred for the housing to be shortened

if they have a bw68 in them it would be kinda stupid to pay to have it cut down when there are one out there already the right size....cant be to hard to put the disk setup onto a 120y diff

i have a 75 120y 2dr sedan that has a hitachi diff in it at the moment. my mates got a se sigma paddokbasha i had a look at it and it has some sorta 4 link in it and down the track i plan to airbag it so it would make it easyer with 4link anyway, stronger also. how much does it cost to get a diff shortend

cut all the spring perches off etc and maybe shorten it the sigma diff comes in borg warner (which will work quite well if yor 120y has a borg warner in it already which some of the sedans have) with discs and thats in the SE and GSR sigma's im pritty sure the sigma's use the same centre as the borg warner 68 in the datto's.

probably be a lot of work, sigma is probably wider and is a 4link? setup. There would have to be some dick brakes that bolt up to a BW 120Y diff, bluebird maybe?

i was just wondering how much work would be in putting a 82 model simga disc brake diff into a 120y or is there some thing a little easy thats got disc brakes
