I believe the Moving Violation kit is from the '70s, and the Hot Rod release was the last one before the MK reissue.
The Moving Violation was originally released in 1976, then reissued in 1997 as part of the Selected Subjects Program. You can see the "Revell-Monogram" branded instruction sheet in the earlier pics of the kit's contents, so I updated my earlier post with that info.
There's 2 axles in some issues of that kit. 1 of them is the regular solid axle with functional steering, the other is a chomed drop axle that does not have the functional steering feature. The Hot Rod variant of that kit is that way for sure.
Does anyone have or is anyone willing to take and post a pic of the second, chromed axle?
