Hey guys,
I've got these shocks I'm planning on using on a current project. It is my understanding that these shocks were used from'38-'48.
I've found info on rebuilding, but not any info on where you can get parts and/or seals.
Please understand, I am not looking for a rebuilding service, I am going to deal with these myself. This is a budget project, and my labor is cheap.
So, I was wondering if anyone knew where I can get seals or anything else for these before I open them up and start figuring it out. Thanks!
