Manual conversion, tailshaft

The distance between the splined gearbox output and the tailstaft mount is shorter on manual than auto. Do i have to just use the front half of the manual shaft or what? If so, does the tailshaft need to be balanced again?

Yes if you seperate the centre uni joint you can just put a manual front half onto it instead. You will also need a different yoke to insert into the manual box as im pretty sure it is different to the auto. If you do this it would be advisable to get it balanced as you will likely end up with a bit of driveline vibration. Idealy would be to source a complete manual tailshaft if possible.

I do have a complete manual tailshaft, but when i put it in, the mounting holes for the centre uni joint don't line up. If i do line them up, the rear part of the tailshaft is too long to connect to the diff. The only way to do it as is would be to move the mounting bolt holes.

How far are the mounting holes out by? Do the lengths/mounts work out correct if you were to use the manual front half and auto rear half or use the complete auto tailshaft with the manual yoke on the end?

Holes are out by about 10cm, don't know if it'd work using the manual front and auto rear, depends where the uni joint splits and what side the mount comes off with. Using the manual yoke on the end of the auto shaft would work. It would mean disassembling the end uni, is that difficult?

Disassembling a uni joint is not hard if you have a general mechanical knowledge and toolkit. I've done a few of them but rather that type up a huge list of procedures i've just attached this weblink which explains it better than I could have anyway lol.

Hope that helps.

You will need a manual starter motor. The auto starter motor has a spindle snout that will not clear the bell housing. I converted a VS using a T5 gearbox from a VR.

The only reason my tailshaft did not line up was because the donor car was a wagon, my car is a sedan. I tried changing the splined gearbox connection, but gave up as i couldn't separate the uni joint. Ended up having to disconnect the CV joint in the middle and swap the front of the manual shaft onto my old auto shaft. Bolted up fine then.

About one more day i reckon before i can reverse it off the stands! Good luck!
