Oooo ... I think I have this exact jack. We have the same number at the bottom of the handle, in front. Lots of questions ... I can send via PM if that's easier.
What is the model and where did you get the seal kit?
You have any history on it?
Did you repaint it to stock colors? Mine seems to have a yellow body, with blue trim, hard to.
Mine seems to be missing a cover, are they still available?
Mine is on the left.
Thanks for any help .... and great job on the restore.
