Hi,
I am a newbie but making progress on a total build up of a replica '29 Ford roadster. I just completed attaching the four bar front and rear ends from TCI and the frame is painted with front 4" Magnum axle and econo disk brakes. The rear is an 8" Maverick rear with 2.79:1 ratio for mileage. I have a rebuilt TH350 with a B&M shift kit and stock converter. I am planning to use a short duration cam in a SBC 350 to try to get low speed torque AND 20 mpg. I am retired but trying to finish the car while I am in reasonably good health. One question came up recently when I found that the TCI bolts for the four bar use nyloc nuts instead of lock washers and there is very little extra thread even after the nuts are pulled up as tight as I can get them. The nuts at the axle ends are only half thickness and I am worried they will back off. I saw a picture of a four bar rear that came apart on a rod run in STREET RODDER a while back, so I have used a cold chisel to nick the exposed threads to make it harder for the nuts to back off. My thought is that after I get the necessary wheel alignment I should tack weld the nuts to the bolts? What do you think? In particular when I attach the bracket for the front Panhard bar to the batwing, there is very little thread left over on the two bolts that hold the right two bars. Comments/suggestions?
