I've got a 1937 1/2 Ton Chevy truck with the original style shocks and have a question, the shop manual says to top them off with "GM Shock Fluid", of course there is no reference to what viscosity oil etc. that is. What should I use for "GM Shock Fluid?
Thank you

Jim Carter's website sells CarQuest Shock Oil and is shown to be the correct oil for 1949 and older Chevrolet and GMC Pickup Trucks.............oldchevytrucks.com/me672.html

Most people these days use motorcycle fork oil or hydraulic jack oil.

I have the lever shocks on my 47 3600. I used ATF in mine. I need to repair three of mine as they leak around the shaft. They work just fine for 78 years old. My truck rides very nice with them. I see no reason to replace them with tube shocks that won't stand the test of time like these lever shock. I replaced the RT front because it was seized and rusty inside. The other three just need new seals.
