Gear Box Worm Shaft Seal

Best place to buy a new worm shaft seal for the gear box. 72 Duster with power steering. How hard is it to change on the car with stock manifolds?

Slant 6?

V8?

Changed the pitman arm shaft seal on a 72 Swinger, that was a PITA but I got the parts from Napa no sweat. That was 20+ years ago though...

Rockauto shows three suppliers, NAPA or someone local should be able to at least cross one of those numbers for you if nothing else.

PS, the FSM is your friend here.

318 with iron manifolds

Dunno how hard it'd be, but I imagine the manifold being out of hte way would help.
