mfg Posted March 28, 2014 Report Posted March 28, 2014 I have a pair of NOS threaded bushing type upper control arm inner shafts. (complete assemblies) I think they fit '51-'52 Studebakers, and Studebakers with R3 equipment. Has anybody tried modifying '53-up rubber bushing type upper control arms to accept these threaded bushing type inner shafts? Certainly welding would be required, Would the effort involved be worth it for a street/show car?
mfg Posted April 2, 2014 Author Report Posted April 2, 2014 I discovered that the welded on 'nut' at the OUTER end of a '53-'up upper control arm is the same one used at the inner end of '51-'52 & R3 arms. If I remove these welded nuts from the outer ends (which unfortunately would ruin two upper control arms), I think they could be carefully welded onto the INNER legs of two other '53-up upper control arms, giving the bushings for the threaded inner R3 shafts something to screw into! Interesting project!

Tom Yes, I agree with you....Performance wise the solid upper arms would be a plus...but these cars already ride hard enough without REMOVING a rubber cushion!
SBCA96 Posted April 16, 2014 Report Posted April 16, 2014 In my opinion staying with rubber is the best bet, poly squeaks and delrin is hard. Metal bushings transfer much harshness. I had steel bushing uppers on the '78 Camaro for a little while and it was too much, that said we are running 40 series tires. Tom
