yep, there are the same size but longer.

I found that the wt ubolts were pushing it.
When I did mine I could just get a full length nut on the ubolt that sits up on the pumpkin

I said before stock WT u-bolts, but that was misleading. I'm sure mine are an aftermarket so are a little longer than stock. Lucky I hadn't got around to trimming them haha!

When I did mine I reused all u bolts except the ones on the front diff driver side.

I found out the hard way putting it together and had to source 2 new one they come close but just. It close enough

The guide on the axle tube is obviously welded to the housing right?
Are they of similar design to the WT ones but to suit a different position?

that part of the housing is the same so if you grind of the n/t one and weld it to the w/t diff in the same place as it was on the n/t diff.

dose that make sense??

NT RHF inside Ubolt is both larger diameter U and longer than all the other Ubolts.
To do it properly you really need the Ubolt guide thing from the top of the NT axle tube as well as the RHF lower spring plate.

that part of the housing is the same so if you grind of the n/t one and weld it to the w/t diff in the same place as it was on the n/t diff.

dose that make sense??

It does. But if its what im thinking.. it'd be easy enough to make one.
