Evening Kelly, so just thought I'd send = a note w/ an update. I did find a fella in Tulsa who has access to a laser = scanner. He's getting me some pricing

I'd like to ge= t an Iron [preferably the side that mates to the front cover]&nbs= p;scanned as well but don't know if you've got one handy [as in, not 'in' a= n engine]. I could always

=0A

do it here in time but that might take = a bit before I get my hands on one that is not in an engine.
