[urq] Help needed: Door hinges pin replacement

[Jim Haseltine]

Now you've got me thinking. If I don't have to head for Leeds tomorrow to
sort out a fuel line on a 85 Ur-q (replacing a leaking compression joint
tonight in the dark when it was snowing was not fun) I'll have a play around
with a screw press.

Regards,

Jim Haseltine
