First off. Thanks biggman100 and moses for helping me get on the board. That is the part in the left of the picture. From what I've been able to find, the 90-91 part is unique to those two years, my friend was able to pull a part # 4338578.
I did find this post on another forum that presents a possible solution. http://dodgeforum.com/forum/1st-gen-dakota/345534-1989-dakota-frnt-axle-actuator.html#post2988536.
Any thoughts on swapping out the guts of the actuator with a new one? If the internals are identical as he says it seems like a viable solution to me.
Thanks again!
