  Looking for the torque spec for the four nuts that hold the front leaf to the frame. Also looking for a publication for a torque specs. 1934 Raodster.

  You need to let us know what year car. Most torque specs were listed in the service manual. Not all bolts had a torque specification from Ford, in those cases, use the standard torque specs for these bolts.

  Specs for a 1934 Roadster.

  I can't find any specifications for torque on the nuts for the u-bolts that hold the springs. Tighten the bolts securely and install the cotter pins to prevent loosening.

  Some other advice on torqueing these nuts be carefull of your own. For some reason the stance you have to take or at least the one I did when tightening these down on front spring led to a hernia operation. The stance I am speaking of was laying flat on my back and must have put all the strain or torque elsewhere,never forget that day.

  I noticed you have a 37 coupe, would that advice apply on a 1934 Roadster too

  37 Coupe, were you tightening the correct nuts??

The nuts don't have to be as tight as you can make them, just enough to make sure that the plate doesn't move and the spring bolt stays in the recess in the frame. The cotter key keeps the nuts on the bolts from loosening.

In 1934, most mechanics, just used the "tighten it to just before it starts to break" torque specs.

  You don't say why you are tightening the U-bolts that clamp the spring to the crossmember. If the spring leaves have shifted, it is likely that the center tie bolt in the spring assembly has broken, and one or more spring leaves have shifted, allowing the spring assembly to move from side to side.In any case, I would replace the spring U-bolt and hardware as a precaution. C&G has them in a kit or your '34. Part number is B-5345-S. I would also order the nuts for the U-bolt. They are part number 1146. Their order line is 800/266-0470. If you need the special tie (center) bolt, the number is B-5345-F. The cost for all should be about $50 plus shipping. A small price to pay for making a valuable 83 year old car better.

  I find that tightening the spring u bolts is best accomplished with the weight of the car on the spring, less strain on the bolts.
