van door lock replacement

[BigDunkyWunky]

Annnnd I'm back.
Keys started spinning in the door locks so I checked out my new Haynes manual for instructions on how to replace them. All seems easy enough. Bought a new set of 3 locks from Neat Car Parts in Birmingham and am about to set about fitting them. Apparently I need a "threaded removal tool" to extract the retainer from the front doors. What thread is it please? And I'll make one up or get a long screw to do the job. Anything else I need to watch out for?
As always, thanks in advance. Cheers, D.

It always used to be that you used a long self-tapper. If you prise out the oblong covers on the door shell edge, you can eyeball the holes.

Cheers addo I'll give that a bash

Done. A length of screwed rod from work did the trick and they were all replaced in under half an hour. Now I think I'll fit a radio :-)

Thanks for your help
Cheers
