Pistons for MC motor needed...

Ouch! Is this really necessary?
a) Careful use of a hone will remove the lip - which might prove to
be more 'deposit' than 'wear'. Measure the bores carefully 15mm
b) Audi's replacement ring sets come with a stepped upper ring. If
fitted the right way round, it _shouldn't_ foul a small lip.

Guess what I have on the shelves. Spelt "Mahle", BTW. They're special
order only with a nine-week lead time. Well, they promised four weeks

GBP400 the set. Plus shipping. There is _NO_ official oversize piston
available for the MC or MB engines. I bought this set to rebuild
MB001293, but that won't happen until the New Year.

Beware of the 81.5mm oversize for the KV engine. Doesn't fit -
20mm vs 22mm gudgeon pin and a different top.
Hey, guys - I could be a middle-man!
