I'm with you CaptMax....I just noticed this thread today!!! First and a little belated,
and second, yes it is possible to mount the IH wheel weights on the inside of the rims. If you look closely in my picture at the rear wheel, you can see kind of what it looks like if you do. I now have duals on the rearend and do not have the weights on this cub anymore.....sorry, no other pictures of it.
PS> Your restoration looks awesome!!! Keep up the great work!!
