Stijn,
in the curved part of the P201 (repro), the holes are very close to the side. A bit too close for comfort even.... Well, actually, the bottom hole is not close enough to the side. It does not fit between the stud and the little edge on the crankcase...
Like I said, some grinding and welding and it shoud work... But I don't have a welding machine....
ps; (I'll have to decline your offer to purchase my car for 500, but thanks anyway
)
