Motor mounts on my ranger are pretty shot. Based on a little bit of digging, It appears to me:
- 2.8L has different mounts than the later 2.9 and 4.0 engines
- 1983/84 have a different frame crossmember than 1985
- 4WD and 2WD have different mounts (because of different crossmembers again?)
- no-one has the drivers-side (left) engine mount in stock for the 4wd 2.8L. Some places won't let you order them. Summit racing offers to at least special-order them (have not tried yet).
