When we ran a full service chassis fab/turn-key hot rod shop a number of years ago, it was always useful to have threaded things around to weld into the frame for some kind of mount, etc.
Here’s a list of all our threaded things for your reference:
Clamp Plate and U-Bolts. For 1928-34 Ford stock or repro front crossmember with a transverse spring. Repro front springs usually have fewer leaves than the original, making them thinner. The clamp plate spacer gets welded to the base plate to make up the extra thickness so the clamping action is on the spring leaf, not on the crossmember.
The spacer plate welds to the clamp plate at each end only.
Since it is only a spacer, and goes between the clamp plate and the spring, the weld is only holding the 2 pieces together. There isn’t any strength requirement to this weld.
Parts included:
Plate, clamp plate base, 4 holes are 1/2″, center hole is 9/16″. This clamp plate will not fit original u-bolts, 15702, 1
Plate, 3-1/2 x 1-3/4 x 1/4″ thick. Spacer for clamp plate, 15703, 1
U-bolt, 1/2″ x 2-1/2″ x 3-1/2″ long legs. These u-bolts do not fit the stock 1928-34 Ford clamp plate, 200210, 2
Nut, 1/2-20 right hand thin nylok, zinc plated, N08FRNTZ, 4
