Thanks mate, it's hard to know whats been done to the truck as a lot of it is not original.

I think it has a 9 inch diff going by internet resources that detail the differences. No ID tags on diff. If the diff is leaking (dripping) oil out the yoke that connects to driveshaft, would that just be an oil seal that I can replace?

Also wondering if anyone can tell me how truck suspension is lifted at the front (like what components are modified)? This truck has a couple extra leaf springs and couple blocks under the leaf springs jacking up the rear to what I'm guessing is a 2 inch lift but I'm not sure what has been done to the front.

Last question, is a power steering box difficult to rebuild? I can get rebuild kits from the states for $60 and I thought I might as well do it if its doable at home in the garage?

Appreciate your time guys
