Im going Mt75 to capri live axle.
Mines on order from This place
They have on the shelf adapters to go from the 3 prong out put of the mt75 to a standard uj. The shaft will also need a sliding section

Ive got zetec to mt75 and sierra prop and diff, and i have kept the original donut. mk shortened my prop and works fine for me. you can buy an adapter
that allows you to remove the donut and have a sliding uj joint, not as locost as first method. Sorry i have no pictures without dismantling my
transmission tunel

I have kept the donut in mine and it has given me 500+ miles of trouble free motoring. And hopefully many more!!

according to the guys on the sierra forum I am on the only reason for the donut was for a smoother take up of power. Supposedly to make the ride
smoother for the upper end sierras.
Considering it was hauling about 1 1/2 tons of car and your puling about 750KG or less I don't think there will be any detriment to removing it

Hello,
I used The Propshaft Clinic for mine. The new prop doesn't use the doughnut, instead I used the transit gearbox flange (four bolt) and the prop
uses 3.5 tonne transit u/j's front and back.
However the rubber doughnut was for taking up the back lash so if you decide not to use it you should ask who ever builds your prop to use the prop
tube that has another tube inside it bonded to the outer tube by rubber (sorry can't remember what they are called!).
These types of prop take up the back lash and protect your gears the same why as the rubber doughnut will.
AND it will make a difference as I didn't use it on my prop due to length + weight of my prop was at the safety limit using just steel tubing
(fitted in a Vauxhall Viva) and it does not feel as smooth as cars with MT75 boxes and rubber bushed props of one sort or another.
Po79.
