Do you need a motor? Its not going to be this week- but I could probably get my hands on one-

79-85 front motors are all interchangeable. However alot of the time it is not the motor but the infamous linkage that is binding. Recommend you do a search because I believe someone has written a thread on how to repair/lube your wiper linkage/mechanism...

the bushings closest to the wipers are corroded, remove the windshield wiper assemebly, disconnect the motor, use liquid wrench/pb blaster/wd 40 on the bushings, move them back and forth until both rotate freely.

Let me know if you need a motor. I have a spare in excellent condition.

Linkage only problem is the bushings getting brittle and cracking. Found out recently how to take care of that problem by cutting down similar bushing and epoxying (very carefully) to the linkage, then greasing, etc. Tight as hell and prolly stronger that stock new.

LOL A pack of them from Autozone in the HELP (motormite industries) section for Nissan Maxima or Altima or whatever. Same diameter but a little too long. Used NAPA 2 part 5 minute epoxy. This works wonderfully.

I also saw where the dealer still carries the short and long brackets for the FB headlight lifts. Each has the exact same bushing on each end as our windshield bushings. But I believe my fix will outlast new bushings.
