Well since I started this thread (some time ago) I'll let all know what I did.

 in a nutshell, nothing. Decided to stick with the spool, putting money to the side to get some billet axles  (Very slowly ).

 As for the offset on the gears being different, I was under the impression the LSD and standard gears were different ,about 10 years ago I tried to fit a 2.77 crown wheeled LSD into my car, hence why I thought the offsets were different.

After starting this thread I compared both 4.11 crown gears i have and realized they were the          same.

 So I did some research and found that yes, standard diff gears share the same offset as the LSD, apart from the 2.77 geared LSD.

I also had a look into if 28 spline cones can be swap to 25 spline cones, as the 28's are easier to find and I want to keep the standard brakes.
 apparently not , they  lock up.

I bought a lsd centre that was a 28 spline 4pinion, but was changed to 25 so i could use stock axles. so there must be some way to do it

Apparently they go in but start to lockup, they don't disengage properly, then lockup

I haven't tried it only what I read. ( possibly they have made 25 to suit 28 these days??)

thats basic,
you just want a 0575 25 spline lsd centre. use your shims and this centre http://www.ebay.com.au/itm/2-Pinion-25-spline-LSD-VL-6cyl-Diff-Centre-also-VE-VF-VG-VH-VJ-CL-CM-Valiant-/230821878457?pt=AU_Car_Parts_Accessories&hash=item35be0e5ab9

i got one of those in my diff atm and ive had no problems and give it absolute shit when i take it out, but soon to swap out to a 0578 ( BTR) lsd centre in 28 spline because i want the stronger axles. ( theres some very good au type axles out there)


i dont know why people still think 9" is the only tough diff out there?, this is not the 1980s anymore and theres parts and ratios for the Borg diff.

Speedy diffs has his te  corty in the 8 second zone with the borg diff.

theres even a 10.7 sec xe falcon on ebay right now with a std cone lsd 0578 tightened ( by speedy diffs no less), hope Wes dont mind me useing his car as a example here..lol  http://www.ebay.com.au/itm/1983-XE-FALCON-TURBO-10-SECOND-LPG-TURBOCHARGED-STREET-DRAG-CAR-UNIQUE-AND-FAST-/150848943868?pt=AU_Cars&hash=item231f4c36fc

so there it is, even 8 seconds on a borg diff no problem, and obviously Speedy Diffs would be a good shop to call if your in doubt on what parts or who to do it.
