Hey All

This is the 1st individual that has requested a MKII differential from me. (Not for sale)
I just wanted to share the condition of this MKII diff, as its one of the lowest mileage / cleanest I have ever come across.
Even as received it was super clean, thought it was worth showing.

I can't say I have seen many diff's with ~30k miles. This has to be some sort of anomaly!
Even the rear aluminum cover is in its original die cast finish. (no sandblasting needed)

I swapped gear ratios for this one to 4.10. (Had 4.30)
Upgraded the LSD with the Weir kit.
Also switched to the solid pinion spacer.

Pretty much the same upgrades I usually do for the MKIII's.

Also took some comparison measurements side by side with the MKIII, just for curiosity sake.
Side shafts/LSD Plates/LSD Construction ect..
Its interesting to see some of the same design attributes that were carried over to the MKIII from the MKII.
Also pretty clear the vast improvements and weaknesses that were corrected with the MKIII.
The MKIV is a whole different level beyond this, but will get to that at some point.

Check out the factory machining marks still on that side gear!

Great pics, Nick. I'll be interested in one of those if you ever come across one in similar condition that, in addition, you have worked your magic on.


Ken.

Yep, this one actually heads to UPS today.
Waited on shipping to try and miss a storm that is coming through the owners area.

Thanks for sharing, always wondered about the feasibility of swapping a Mk3 diff into another chassis like the Mk2.

You could possibly do it, but quite a few differences between the MKII and MIII differentials.

Just mounting to subframe alone, the MKIII has 2 large vertical mounting points on either side of the pinion and 4 horizontal on the rear cover.
The MKII is very different in comparison.
As you can see from the photos I counted at least 8 points in the case where it appears to bolt in. Though I have not personally owned a MKII to know if they are all used.
Then the physical size and smaller flanges / bolt count as well.
Anything is do-able just have to put the work in :)
