Here's my concern about 60-62 installs-
your mount on a 63-66, fits great!
Looks like the boxed 60-62 frame is not quite as tall. The red mount that Jake uses looks like a horrible fit on the older frames. Maybe a slight bit of repositioning away from the factory angle will make it line up to the frame better, but will that hurt the functionality of it?
This "I think" is the REZ kit that Jake Groby used on his 60-62. Kit says 60-66 I believe. note bottom left has stud due to frame location, top right is also problem, instructions say to notch frame??!? Seriously?
slepysal did the CPP 60-62 specific kit and used a $20 part on top of that for his steering shaft. From his thread:
not sure if the CPP kit "tweaks" the mounting location a hair clockwise to make it work better, but this is obviously the same 73-87 box bolt pattern, and it fits on the frame at the top right, and under the frame on the bottom left. Makes me wonder about alignment changes from stock, but if it works (I assume "yes" since it's in production), this kit looks far better than the other.
