I can help with this as I've done a number of power window conversions and specifically twice on exactly this application.

Have you seen this thread?

Power window, power vent, power lock conversion - Canadian Poncho (activeboard.com)

65 and 66 are the same, 64 and older is different, 67 and up is different. The regulators must be from a 1965-1966 full size Chev Olds Pontiac or Buick.

I happen to have a set of regulators for 65-66 hardtop here right now so I can get you some pictures for comparison.

To test them, hook up a battery ground to the regulator then power up either one of the 2 terminals in the motor. Regulator should move one direction, if you remove the power and power the other terminal it should move the other direction.

 

 

Ouch, so there should be lots drilling involved?

I big hole in the metal behind the kick panel for the inner grommet on the boot.

4 very small holes in the inner door skin to mount the regulator. That's it for drilling.

 Are there dimples on the inner door skin to guide where to drill?

Hey there, I'm starting this separate thread to walk through the process and discuss any issues related.

 

So I got the kit, which harness looks like it's from 64 according to the wire colors.

Thanks to advice of the experts I figured that the plates were the holes for harness should be on 65 are able to be knocked out, will test that once I get correct conduit boots.

I cleaned and lubed all the mechanisms and motors and now 8 have a couple issues. 

1. I'm not 100% sure mechanisms are from 65. What's the way to figure out if they are 65 or 64? And if they are 64, will they fit 65? Door mechanisms have 7788 stamped on them and that seems to be the only identification, quatrers have 16 stamped. Motors seem to be the same for 64 and 65, but can't confirm.

2. I layed evening on the ground, hooked to battery power and got nothing. I assume they need to be grounded? If so, what would be the best way to test it without mounting everything?

 I'm not positive, but I don't think those are 65-66...

And here the kit posted as 65, the fonts seem identical to mine except this short lever embossed reinforcement missing on his. (maybe they did an upgrade some time due to lever failure?). 

The rear ones the guy selling don't look like they are from 2 door though.

Ok, let's start with a front.

Pivot to centre of scissor on the long arm  11 5/16"

Rollers on the scissor arm 14 1/4"

Pivot points on the big gear and the end of the long arm 4 1/8"

 

Mounting bolt holes  8 1/8" apart on the long side

 

And a shot of fronts and of rears. As you can see I have them zip tied so there's a pair in each picture.

 I agree with you, your fronts look wrong. Your rears are fine, mine even have the same number inked on the motors as mine. 

And none of your front measurements correspond with mine?

Well, just to be 100% sure I checked the factory installed power windows in my 66 Grande Parisienne. First thing I checked was your green measurement of 11 3/4" and there is no way that is from a 66 Bonneville 2 door hardtop. The measurement on mine is 14 1/4" just like the regulators out of the car that I measured for you.

But your rears are correct. I wonder if maybe he had two sets, one from a 2 door hardtop and one from a 4 door hardtop, and got the fronts mixed up between the 2 sets?

I just can't figure it but you certainly won't get those fronts to fit your car.

will check, thanks

So you took the spring off the hook and wound it up one more round?

If you didn't do a full turn what did you hook the spring to? Somehow I can only picture it going a full turn to hook onto the same tab the factory hooks it to.
