stakeside Posted January 7, 2017 Share Posted January 7, 2017 Looking for a source for my window regulator spring. It measures 2 1/8 inch diameter. This is for my 29 DB truck. "WPC" and "Pat No 1651" is stamped on the arm. Link to comment Share on other sites More sharing options...
nearchoclatetown Posted January 7, 2017 Share Posted January 7, 2017 Stakeside, I see the ear is broken off the lower one. Spring steel is fairly forgiving. You MAY be able to bend a new hook on it. Clamp the end tit in a vice and work the bend around, might use a brass hammer. It's already broke, nothing to lose. If you bought a piece of raw spring steel you could easily bend a new spring, it is very soft and easy to work. THEN you would have to heat treat it. Follow instructions in a Machinist handbook. Spring steel should be available from McMaster-Carr, the best restoration supplier I know . Link to comment Share on other sites More sharing options...
Ron Lawson Posted January 7, 2017 Share Posted January 7, 2017 That type of spring has been used in window regulators for years Possibly one from a newer vehicle may have the correct dimensions for you Link to comment Share on other sites More sharing options...
jpage Posted January 8, 2017 Share Posted January 8, 2017 Restoration Specialties in PA has many of those type springs. You would have to send them a sample to match as all I.D.'s are lost. Give them a call at 814-467-9842 9-5 EST. Link to comment Share on other sites More sharing options...
Pete in PA Posted January 8, 2017 Share Posted January 8, 2017 18 hours ago, Ron Lawson said: That type of spring has been used in window regulators for years Possibly one from a newer vehicle may have the correct dimensions for you I work on cars just about every day of the week and it's astonishing to me just how similar some fairly recent production window regulators are to that 1929 part. I just put a window regulator in a 1990 Mercedes Benz and, apart from the fact that the MB part had an electric motor attached, that regulator and the 1929 part are practically twins.
