Hello Paul,
Thank you for the photos and information... Would the new shaft shown in your photo be available from Jim Carter or Chev's of the 40'S? I suppose I could drill my original pedals and tap the threads, unless you had a machine shop do the work? Then again it may be easier to find the hollow shaft you speak about with the grease fitting at the end... Would accomplish the same thing... Certainly better that what I have now...
Philippe,
Unfortunately the typical vendors don't carry the shaft. A friend made mine for me. I drilled and tapped the zerk fittings, and I am no machinist so with a little care you should be able to accomplish the task as well. The bushings are available from the aftermarket folks, but I found that the dimensions of a piston wrist pin bushing for a 1940-50 something Ford flat head V8 engine happen to be the same as the Chevy pedal and shaft. The part number I used was Clevite 2233451. At the time I restored my 42 truck, I happened upon the bushings on ebay for much less than the aftermarket sources.
Best of luck with your project, those 1939 bigbolts are fine looking machines.
Paul
