I'm currently using a Gripper LSD (from matt humphris) on my 160ftlb turbo k11 with a 30/65 ramp and one-sided clutch pack to fit the speedo gear.
I use it daily with occasional trackdays.
when I first received the diff from matt, it was a normal dual-sided clutch-pack LSD (clutch on both sides of the planet gears) with a 2-way ramp. This type of layout would be more durable and consistant between left/right turns and recommend this type for rallying but the size of both clutches meant there's no room for the speedo gear.

the next version was a single-sided clutch LSD so I can fit the speedo gear, with a 45/45 ramp and heavy preload.
the 2-way ramp and heavy preload on public driving developed sudden inconsistant handling when acc/braking during turns and so much loud chatter it eventually shattered the preload beville ring.
dunno if its cos the earlier preload ring design was weaker but it happened afew times.

now on its 3rd rebuild with a more progressive 1.5way ramp and less preload and updated new version of the beville ring, the locking action is very progressive and seems to be much more durable

You'd just need the corresponding pinion gear to go with your choice of crown wheel
and a big press / puller

the pinion is integral with the output shaft aint it paul ?You'd just need the corresponding pinion gear to go with your choice of crown wheel
and AOC did a group buy of RS5F32 helical diffs a while back (different diff to the type 30 and 31 ones tho)
Ah sorry Frank, i thought it was just the 5.1 that had the integral gear on it as an an "aftermarket" part. Didnt realise the OE ones were the same

Actually, if you had a new pinion made up and access to an external cylindrical grinding machine you could do it fairly easily. Dunno what the mantime would be though so could be costly to get it done by a machine shop... almost definately pricey for a custom pinion...
Edit:Thats change the pinion on end pf shaft, not other gear pairs

I run a hockly diff. I did'nt really know What type off diff to run but after a discussion about the type off road ralling that I was doing, thay built machine a diff for what I needed. The ramp angle and the % of slip that I needed. All I can say is that Hockly did a top job and for money It was well spent.
