Searching for used G63B for 1987 D50

I recently bought an all original, unmolested, garage kept ‘87 D50.

I was hoping it was just a bad starter but it was much worse than that.

The counterbalanced belt broke and the motor oil staved. I have searched my area (southern West Virginia) and came up empty trying to find a good used motor. I’m hoping this is the place to look, I’ve heard a lot of good things about this place.

This is my only transportation and I would like to move forward on this project as fast as possible. Thanks in advance “GTP”
