On disasembly of the motor I found the plastic plugs severly lopsided due to all the years of strain, new plugs cost $8.00 at Autozone or Amazon, other than that the Autozone Ford Mark VI would have worked $ $44, but I saved myself $38
Just rplaced my 25 series Kwikee step motor with a Dorman 742-277 window lift motor for a 1986 Ford Taurus driver side window lift motor. They said the Taurus had a high torqe motor which is why the number ends with 277 meaning high torqe. My steps zip in and out with this motor application. It was a special order item but only took one day for them to get it to my local AutoZone store. I also noticed AutoZone had rebuild kits for Dorman window lift gear boxes (plastic gears) in the Help section of the store.
