Tom, I have a restored high cab '36 also. Somewhere I have a list of options and I think the shocks are listed. The same shocks fit '36-'49. I can look for that list if you like.
I can also take pictures of the shocks and their links to the axles but I have no computer skills and I don't know how to post pictures here. I can email them to you. My email is
[email protected].
I also recently converted my '36 from 4.11 to 3.55 gears using only OEM Chevy parts, no expensive aftermarket stuff, if that interests you.
