I put Moser in the black car and the wagon. The wagon is not stock length. The black car was, although I did take 1/2" off the passenger side tube to move tire in for more clearance. My guess is the body is not quite perfect and the 10" rim made the RR tire rub on the lip if anyone was riding in the back and hit a bump.
I can dig into my papers and see if I have the sheet, but that was near 20 yrs ago. I used to have all the old stock axles, but did a scrap run a few years ago and pitched them all.
Best to just jack it up and pull them. Sorry, not the answer you were looking for.
