Quote: It's a Dodge /Plymouth wheel stud pattern. Thats 5 studs on a 4-1/2" pitch circle diameter [or 114 point something mm for metriphiles]
Ford copied it after it had been in continuous use for seventeen years. [since November 1931]
The true "Ford" pattern [1928 to '35, then '39 to '48] seems to have not been used by anyone else that i know about.

Just put a rotary in it

I've just measured the diff & it is 1250mm from outside hub to outside hub.

For those people who arent aware that you will need to shorten your tailshaft to suit this setup.

This diff is also 5 stud - ford stud pattern so your standard wheels will not fit unless you reset the stud location on the axles.

I'm not sure if it will fit in a 1000ute?

I will take a measurement from wheel hub to wheel hub when I get home.

The diff housing, axles and brackets are the only things have been modified
Axles are 30 spline.
Has 4:3 Gear ratio and carrier is standard open wheeler but can lock it if need be.

I'm in Sydney, Blacktown area.

Diff will fit in ute for sure, but dont know if coupe or sedan's are the same dimension.

These diffs are very tough and have been proven to handle 500hp

Never used since built - work done by Craft Diffs, standard hilux brakes with new brake lines.
Can also supply complete with tramp rods, new wheelie bars and reset leaf springs.
Diff only $1000ono or the lot for $1400
