I just Grabbed my older brothers 1990 SWB 4x4 4 cylinder pick-up. It runs pretty decently but he hasn't done a thing to it in Years. It has 154k It needs a new rear bumper and the drivers side door is all rotted away at the bottom. It also needs a set of Wiper arm Assemblies. Any ideas?

 

change all fluids and filters.
change plugs
use some bondo maybe for the door and paint the whole truck if it needs it (search on here for a diy paintjobs some of them look professional).

wiper arms you can get from a salvageyard. i would start looking around.

 

Check wiper arms from the dealer. I found the prices to be reasonable and saved me valuable time hunting around the salvage yard for good used.
