When I first started reading here it was because I was looking to fix the problem of rubbing 33's in a solid front surf.
With help from people here, I made my mind to try and move the front diff forward instead of the equally (or more-so, time will tell) simple of idea of lifting the body.
I chose this path because my wagon already has had the springs reset and its high enough for me.
Also the hassle of going to crossover steering is beyond me at the moment, this first.
Anyway back to Maverick..

I said then that I would get onto tis in 2 weeks, that was 2 months ago

To describe the plates they have a stud or nipple in the center at 16mm diameter that fills the hole here...

This picture tries to show where the plates (one per side) go and approximately where the location pin normally resides.
The horizontal is the plate, the other is meant to show the pin.

Might just add this now. If you want bigger photo's check my album, Timotheus' Randoms[/i]
So the nipple faces down into the central hole, the idea being that the other holes replace it and that the hole the nipple fills locates the plate.
The holes on the US ones are at 3/4" and 1". So you can rotate them 180' for either 3/4" or the full 1" relocation.
Its relevant to understand that 3/4"-1" is about the most you can get without having to mess around with drive-shafts and more.
So I see this as a simple solution to one problem.
The plate has to be a minimum thickness to prevent the location pin (I don't have a photo of one now but ill try and get one later) from fowling on the axle perch.
My estimate for the thickness is 12mm, Thats the figure I gave the guy making me a set so if they don't fit I'll post a better size.
So the pin will be about where the red dot is below.

So if you have a hole there like the above pic demonstrates then the diff should be forward by however far the nipple and the hole you're using are.
The plates thickness will impact on the total height your U-bolts have to hold, my reckoning suggests that 12mm will be fine, but Ill see when they are in.
For now thats all I've got.
Someone is making the plates, ill get them as I get the front seals sorted and a LSD fitted up front.
Once they are in (and as they are are getting done) ill try and keep the photos coming.
