There is welding for the 6 speed but not for the W58, theres a complete conversion for sale on here at the mo.

Its fairly tricky, you need to cut a hole in the bulkhead, install a clutch cylinder and hydraulic lines, piss about with wiring, remove/modify pedals so not for the novice really.

By cutting a hole in the bulkhead, if you mean for the clutch pedal, it's already there so no cutting required. The only cutting required is for the replacement of the transmission tunnel.

Just to add - it's not necessary to weld in a new trans plate (though would be good if you have the tools). It's enough to bolt and bond it in place. I don't think the stock plate is welded in from the factory either.

 

One other thing that's often missed on these threads is a support bracket for the clutch slave line needs to be made under the car, this is welded in on the factory cars, bur could be safely done by a bolt.

 

Provided you have some good jacks and ideally a geabox jack it should be a reasonable job for a competent DIYer. The only thing you may need a professional to do is allign the prop shaft mounting shims

Really? So auto cars come with the hole? I assumed, incorrectly, it would be uncut. Is there a bung fitted then?

I needed to drill out the two holes for the clutch master mounting bolts to go through on my '94 car, the centre where the arm goes through only had a gromet as Tony mentions. It easy though as the two drill holes are already stamped into the bulkhead sheet metal.
