Datsun-San Posted October 29, 2012 Report Share Posted October 29, 2012 I'm pretty desperate for a passenger side window regulator for my '74 260Z. I recently picked up what I believe now to be a late 260 or 280Z regulator (listed as being for 260Zs in general) which is too wide to fit down the channel into the door. At the moment, I'm relying on the Z as a daily driver, and have to drive with the window wedged by the classic handy block of wood. Even then the window is still 1/2-1" open. As winter rapidly descends on us, I'd like to be able to keep the interior (and its occupants) away from the exposure of the elements and instead focus on other repairs that need doing. Any help would be greatly appreciated! Link to comment
Ranman72 Posted October 30, 2012 Report Share Posted October 30, 2012 pics of what you need just to make sure we match it up measure across the 4 screws that hold it in should be about 5 inches I think the 240 one might also work Link to comment
Datsun-San Posted November 1, 2012 Author Report Share Posted November 1, 2012 So what I know is that the two types of regulators I have (the original versus the ones I picked up) have a different shape and measurements from one another. The part numbers are also different. The original is marked "3-12-1RH", while the other regulator is marked "2-10-2RH". I'm guessing the regulators I picked up are from a later 260z/280z and were mis-advertised as being for an earlier 260. Easy mistake to make if one doesn't know model changes, but it is my fault for not comparing the regulators in the first place. Anyway, I've included pics of the two parts side by side, the original is to the left while the replacement is to the right. Thanks for getting back to me! Note the distance between the holes for the screws. Link to comment
Ranman72 Posted November 2, 2012 Report Share Posted November 2, 2012 the one on the right with the Teflon tape looks like the early one is this the one you need Link to comment
Datsun-San Posted November 2, 2012 Author Report Share Posted November 2, 2012 the one on the right with the Teflon tape looks like the early one is this the one you need The one on the left is the one that came out of the car. We tried to fit the one on the right and the mounting screw holes don't match up. Let alone getting the thing down into the door. The shape is totally off. I checked around for the part numbers, but to no avail in comparing the early '74 regulator design to anything else. The shape of the 260z regulator out of my car looks much closer to that of a 280z. The longer crank spline, square mounting piece, and lack of a hole between that spline and the spring seem to indicate this. The other regulator looks like that out of the 70-73 240. But I'm still iffy as to whether a 280z regulator would be compatible as the window design changed in '76 for 280s. That and the part numbers on the arms are all over the place. Numbers differed for each example I looked at. The more you know I guess... O_o; Link to comment

Ranman72 Posted November 5, 2012 Report Share Posted November 5, 2012 what is the manufacture date on your car does the door look original Link to comment
Datsun-San Posted November 6, 2012 Author Report Share Posted November 6, 2012 My car is a November '73. But as it looks, the 240z window regulators don't match to that door. Link to comment
