I HAD.. wondered about " the source" of those RG'S Wheels myself Jim !
Was yours stock..or did you ..add..3Disco ?..can't find any pics of them
Wonder..IF.. anyone makes a Boss Kit.. for ZT/75'S ETC ???? Motolita don't.. was toying with idea of a.. none oem.. Walnut Wheel..or a smaller Leather Wheel ie 12".
BUT.. of course..then no A Bag/switches ! Wonder if air bags make much difference ..ar the end of the day ?

I find the wheel, as is, a little bigger than I'm used to.. it's 14" isn't it..shocked me when measured the other day.. thought it was 13" !!!
( as the vicar said to the nun !!! )
