Evening Kelly, so just thou= ght I'd send a note w/ an update. I did find a fella in Tulsa who has acce= ss to a laser scanner. He's getting me some pricing
on what it would cost to ge= t the job done. I'm thinking it might be a good idea to get both the Mistr= al housing as well as a Renisis Front Cover scanned?
I'd like to get an Iro= n [preferably the side that mates to the front cover] scanned as= well but don't know if you've got one handy [as in, not 'in' an engine].= I could always
do it here in time but that= might take a bit before I get my hands on one that is not in an engi= ne.
 
I'll keep you posted as thi= s goes and see where we get.
