lumbersawyer, Perhaps this old Chevrolet filmstrip for
Rebuilding Slides for 1937-49 lever action shocks found in Brad Allen's "flickr" site may be of help in answering your question???
From what I read in those slides and
Pg 2-11 of the 1947 Truck Shop manual, leaks around the shaft are noted as not repairable and require the shock to be replaced.
There are several vendors that offer rebuild services though. The
Filling Station will rebuild your originals, or you can get already rebuilt rear shocks
left 1/2 ton and
right 1/2 ton from Jim Carter. Hope this info proves helpful.
