If you have owned and driven one of the early trucks with the dual wiper motors--then you have probably had one fail on you while driving in a down poor. Finding original motors or restorable motors is getting harder and harder. So I decided to go look over on the "dark side" to see if I could find another option that still looked stocked and had the same wiring. Browsing over some JEEP websites--yes I know-- I found the perfect solution at a decent price--$45.00 for a stainless steal brand new motor.

The motor has a slightly different configuration which will require one to shift the wiper wiring harness slightly to accommodate the new motors---depend on how much your harness has been played with you may need to add a small extension to the wiring under the dash. Here are some photos comparing the two motors and showing them installed:
