Depends on budget and axle.

If you have a sierra rear axle then a standard sierra LSD will come in at around £250, a custom quaife etc will set you back £1000 by the time it's all fitted up.

Unless you can really drive I doubt you would gain any advantage paying the extra, spending the balance on lessons would get you around the track faster.

that's dropped from 150 to 120 in a week.. it's a 7.5 inch diff.. measure the mounts on your chassis to make sure its not designed for a 7 inch..

thats the width between the 2 top mounting holes in case you didn't know..

You will also want the associated 1/2 shafts unless yours are bolt on.

It is unlikely that you have a 7.5" diff which explains the price drop, you need to measure up and have a search on here "lobro" to determin if you have bolt on or push in half shafts.

Easy way to tell which diff you have is to look at the top mount bolt
1 long bolt and its a 7" diff
2 bolts either side its a 7 1/2" diff
Bolt on half shafts come in 100mm and 108mm pcd
The 7" or 7 1/2" measurement refers the crown wheel size not the top mount width although the top widths are similar to crown wheel inside

If you are asking me i can't answer your question as its not me selling the diff parts its Wadders that is.
what i was thinking is you could put the LSD parts in your diff casing
