ok so i bought a r31 diff with the brakes and complete
i havent picked it up yet but have been told it needs to be cut down 100 mm. 50 a side.
does anyone know a local place that will do a decent job
and will customise the tailshaft to suit.

cheers.

yellow pages, driveline specialist

just curious how much was the diff?

cheers mate so a driveline specialist will cover the lot :)
whats a rough price idea?
oh and i paid $150 for the diff at the wreckers. good bloke.
had 3 to choose from tried to find one that was lsd for me but no luck , looks like the welder will be cranked up. :P

thats cheap.. unlucky its not an lsd but

wouldnt be paying more than $200 for a complete open r31 diff

driveline specialist should be able to either do it or point you in the direction of someone who can

think around $1000 is a pretty normal price for shortening the diff, its cheaper if you cut all the r31 mounts off so you arent paying for someone elses time
tailshaft, $100ish to just shorten. dont know how much for swapping a yoke

You only need to shorten one side of a r31 diff as far as i know as they have a long and short axle.

yeh price varies but i have been quoted as little as $650 to shorten the housing, axles.. and respline.

650 is cheap, i got quoted 1200

$650 doesnt really seem that cheap if you actually know what they are doing, and if you have cut all the mounts off yourself

as all they need to do is get one axle cut down and resplined. say $100-150
then they just cut a section out of each side of the diff adn weld it back together in a jig to keep it straight

obviously price will go up if they have less experience with it as they will be charging you for time to measure and figure out how to cut it down
