Its an 89 with an ax15/231J swap. Mj D20 rear and mj cad D30 front. It used to be 2wd but I've converted it. Haven't made a front driveline yet so there's never been one in it, and the vac system never got hooked up for the axle either. I don't *think* the noise is the chain, i think it's teeth touching somewhere and binding on something but i don't know. The shift fork plastic pieces i changed for new ones when i put new bearings and chain in it. The planetary is the factory one that came in that case. I put it back in the way it was taken out.
