Hi David;
Sorry to hear about your engine failure, but as I'm sure you've already
deduced, far better to happen at home than at OSH.
   I'm not sure you're interested in cross border services, but Adam at RX7
Specialties in Calgary, Alberta is very helpful. Last time I had my engine
apart I called him to enquire about having the irons lapped. He could do it
but for a few bucks more he just sold me some irons that he had that were
already lapped and in better overall condition than mine. Due to not having
to pay to ship my old ones to him, it was actually a little cheaper and
much faster.
  And for you the dollar is worth more up here, so that should offset the
cost of shipping from up here. But if you choose to send your irons up
here, do not ever use UPS. Any of the other couriers are fine, but UPS has
very expensive brokerage fees, that are nothing short of piracy.

Todd
(when I get mad about shipping costs and exchange rates, I think about the
boys down under and then I don't feel so bad)
