Call Rex at Williams. *By the way, he took out the Polish wheel/brake
and installed a 5inch Tost drum brake. *BIG improvement.

Already in contact, awaiting specs if he has them off hand...He's
pretty busy right now, and I thought I may be able to jumpstart my
thought process by checking with the experts here ;-)

My ships' gonna get a Cleveland (5606 rules!) disc, which is also a
big improvement on the self actuating model my 59 also came with. The
5.00x5 Cleveland is indeed a close fit, that does require it being a
little off center in addition to a bit more work to install, but so be
it. I'm sure you've spent plenty time looking at these pics, but...

I solved the riddle from those photos BTW. It's NOT a 40-103 wheel,
but rather a 40-78* and Rex was actually the one that did the original
conversion, for the previous owner of that particular Jantar 3. Those
pics are from the restoration/overhaul the current owner did...

* (or one of it's equivalents it's lumped with in Cleveland's tech
drawings. Unconfirmed, but there' s little room for interpretation if
you review Cleveland's 5.00x5 line http://tinyurl.com/5nj32r -.pdf
alert!)

A Beringer was my first choice, but I got a good enough deal on a
Cleveland that the choice was basically made for me...

PS. I got really cool push button flush latches for the vented
scoops, just haven't had time to mess with it for a while...
