nope.
I have been working on a "tech tip" article that covers these wheels, and your possible solutions. Hope to be done soon...

That would be very helpful Grigg! brakes and wheels seem to be the biggest questions on the big bolts. I myself am trying to figure out if I have "widow makers" on my 1970 C50. All 6 wheels are the same and look original, there is no small outer ring and they are tube type 8.25x20 . I have tryed to decifer what type they are from previous posts but still not shure? I know they are Illegal here in massachusetts, and I am getting ready to put my truck on the road soon. wondering if I'll have a problem. also I have NO SPARE! and need to find another tire/wheel to fit it. when did they stop making widow makers?
