Need help with power window conversion on 66 Coronet

[Mopar4Speed]

Ok so I figured I would give an update. There is another issue I have run into. The arms are very different between the regulators as such are not directly able to be used. The manual regulator uses a pedestal for the end of the spring to curl onto so there is a large gap in the arm to accommodate it whereas the power regulator arm just has a hole drilled. I have heard of people cutting and welding the arm shorter when swapping c body ones into a b body. I would prefer to simply redrill and remove the original roller. Would anyone have a 66/67 (or maybe 68-70) power window regulator arm they could measure from the spring center to the roller rivet?

Here you can see the difference

It will be the same as your manual regulator... the plate mounts on the same location, the window is in the same location, the arm length will be the same...
