OldIHC

a little bit more information. As far as I can tell, these shocks on my 1949 KB-3 are single action Delco-Lovejoy, and were used on Chevrolet trucks too. Models 1430-xx and 1431-xx. Here is a link to a portion from a service manual. Boy was that hard to find

So pretty much all there is to do to these things is clean them and put new oil in them.

Just a confirmation, I ordered these and they are a perfect fit.

Thank you! I love the info shared on this site. I think my restore would be impossible without it.
