Several here in Flawda have been wondering the same thing. forbigpicture is traveling down around Don's area and we both have tried to contact him on pm. I missed Brad on the way by going south but am hoping to hook up with him when he goes back north. Hope Don's ok! Haven't seen any posts lately...
WOW, I just noticed this old thread and that I left you guys hanging ! Sorry ! This must have been when I went into the witness protection program !
Midnightcaper, it might be a couple of years too late, but to answer your question, the axle is a 46 inch from king pin hole to king pin hole model, and the tires are 5:60 x 15 bias plies.
If you are still around, sorry for missing these questions.
