What I need to know is if anyone can remember how much they had to shorten their drive shaft! I have recently Installed a A14 with a 60a 5speed gearbox and Ive also changed the front cross member over to a Ute one.. so I dont have to worry about making mounts etc! Today I just finished installing a 1200 Ute/roadster diff (h165) and I went to bolt in my drive shaft and I noticed that its to long.. I can do all the cutting and welding etc myself, Ive got no problem doing that sort of thing but what im not to sure about is how much to take off. As the suspension moves up and down does the drive shaft move in and out? Any help would be appreciated!

You want about 20mm play in the tailshaft, you can munch the seal in the rear of the box if you don't when the suspension compresses. My local tailshaft place does a cut and balance for $88, $40 for each uni if they need replacing, works out a lot easier than cutting and welding yourself and still having to get the thing balanced.

Just get the ute tailshaft that matches the ute diff. It will work, as the coupe and ute are same wheelbase. Also the 60-series 5-speed and original 56-series 4-speed are the same length.

Might even be cheaper to source the right tailshaft than to pay for a shortening job.

yeah like dd said, just get a ute tailshaft
