Thanks for the reply guys, much appreciated. I am learning for the conversion with the LSD box as it will hopefully save me time and money if i do work the car later. The cost of going with a half cut and getting the shop seems to be similar, but wouldn't the added warranty from the shop on the box and labor be the better option? at least with the box they supply based on their words is one they rebuilt themselves and so they can warranty it where as a box from a half cut which may be low kms but doesn't necessarily imply its in good condition so if i put it in and it dies i'm shit out of luck. In the end i don't mind shelling out a bit more for the piece of mind considering a job this big.

I really don't want to repair the box, sell and buy another eitherr because ive already got some mods (exhaust system, teins) and it also takes me into the world of used cars again and i don't know what may be wrong with them where as with mine i know what is and what isnt.
