Recently swapped the standard H150 diff in my 120y wagon for a H165. The tailshaft is now approximately 40mm too long is there any standard datto tailshafts I can use? Or do I just have to get this one shortened?

You want a ute shaft. I have one that needs unis replaced. But they are "non replacable" which means you need a tailshaft guy to replace em. Stock ones are a bit weak so its worth upgrading them at the same time. $100 for the shaft I have. Maybe someone else will do one cheaper.

Auto h150 maybe

Ute shaft should do it. About 40-50 mm shorter seems about right.

Both H150 and H165 use the same flange, but the H150 is only 4 mm different from H145.

Overall length (A+B+C)
* 1334 mm B110
* 1330 mm 120Y (H150)
* ???? mm B120 (H165)

Ah ute tailshaft makes sence will try and track one down thanks guys.

They can be found Stuey but for the time and money i would just get yours shortened.

Rallycar is kindly going to lend me one so I can move the wagon around. Will get the other one shortened when A15 and 5 speed go in

Awesome bud I have one but freight etc.. would be dearer than shortening in my experience.

Hey mate,
Just food for thought,could be an option if your still going to pay someone to mod a tailshaft.
maybe get an aluminium/alloy tailshaft from the wreckers and get it modified to suit?
Some ford models came with aluminium tailshafts from factory.
