Thanks to everyone who has answered my post.  Please keep any other helpful 
info coming.  My goal is to find a 38" wheel that will fit over the cast 
center for the original 40" thus keepin the appearance as original as 
possible.  I would have no problem fabricating the brackets that weld to the 
rim for mounting to the large cast centers.  Guess I need to grab a tape 
measure and find out exactly what will fit.  I have already checked Ebay and 
will continue to watch the site.  There is a set of grill screens up there 
now but they look a little rough.
