Picked up a 68 521 L20B swap lots of nice work done but and there always is a but the original owner decided to remove the entire wiper assembly motor arms and all and toss them out the with the trash. (was going to build a salt flat style truck) So the million dollar question or questions are where would I find all that? is there other years or models that will work?

Thanks
Greg

Any 520 or 521 will work 1965 to 1972. If you use the 521 it is a 2 speed motor and you will need to ad wiring and the 521 wiper switch to get 2 speeds.
