Next on the agenda is the diff....when they say you'll never get those hours back on your life,my diff comes to mind
Here goes....the idea was to fit a minispool to my diff,i located 1 very cheap,hardly used.
Disassembled my S1 3:08 open centre diff to use the carrier for the spool.
Fitted spool to carrier.
With the LS1 and 6sp i wanted to go 3:73 for track work and get some use out of 6th gear.
A mate at work had a set of 3:73 gears which he no longer had use for,so i grabbed them.
Fit pinion to housing,BUGGER 3:73 pinion has a larger shaft diameter and larger bearings and the crownwheel doesn't fit my housing.
A call to another mate,he has a later model dead 3:07 lsd with the larger cast opening for crownwheels.
Pulled that apart,press in the 3:73 pinion with extra shim for the crush washer and torqued up.
Next up,fitted the 3:73 c/wheel to the open carrier and torqued up the bolts (LH threads)
Fitted the assembly into housing and screwed in the side bearing caps...FARRRRRK...fatter crownwheel and early carrier with a different c/wheel face offset so caps dont screw in anymore
Disassemble c/wheel,carrier,minispool and have a play with the LSD centre just for kicks as the spool doesn't fit LSD carriers because of the offset spider gear pins.
Was told that i needed a later model carrier with the correct offset etc,a local c/dore bloke i've been dealing with had a couple of VZ 2:89 diffs which nobody wants.
He said i can have the whole diff for $20.00
Disassemble that diff for the carrier and check the offset
Began fitting the minispool to the carrier,knock in the long pin
then onto the 2 short pins
FAARRRK later carriers have offset pins like the LSD.
It was a case of the wrong minispool or dump that idea with MANY wasted hours and swearing and just give up
OOOORRRR get one of the these

Shoved the whole lot under bench and ordered an Eaton Tru-Trac and live happily ever after
I would have loved to support the local business' but most of them quoted me $750.00-$900.00 just for the Tru-Trac centre.
Went online to Summit Racing in the US checked for Pontiac GTO/Holden they had listed...Price to me $479.00 plus $87.00 postage.
Landed at my door in under 2 weeks and fitted up an hour ago.
Oscar at Summit Racing was great and no hassle at all with emails and tracking the part.
