I have a 79-84 mini 4x4 PS settup for my 78 fj40. My gearbox is leaking excesively where the pitman arm attaches. Could someone please show me a parts diagram for the gearbox. I ordered the outer seal but I'm not sure what other parts I would need or can get. The picture shows a rusty looking PS fluid, I'm just getting my fj40 back on the road so this mini settup had been sitting for a few years. I thought I had all of the old fluid out before I put the new fluid in but I guess I didn't. Any insight would be appreciated.
