Can replacement upper control arm bushings be found? The only way to replace them I've found so far is to buy them on the arm from our host for $80 per side This is if a 1960 1/2 ton 2wd. Also...has anyone replaced their front wheel bearings on a truck like this? I'd like to see if I can get roller bearings locally to replace the old worn out (I assume ball) bearings in currently. Thanks!
