j stevens 59a parts needed

hey folks,
my uncle has a j stevens 59A he got from his dad (my papa) when he was around 10 years old, he is 76 now. he thought it had been lost, but he ended up finding out it was at his brothers house. he now has it back, but his brother lost the ENTIRE magazine assembly.
he has asked me to help him put it back together. i have been able to find everything except the "filler block", it is the spacer between the magazine and barrel, and the "magazine tube yoke", it is the clamp that holds the magazine tube to the barrel.

trust me when i tell you, i have looked, and looked, and looked! if anyone has any info, i would greatly appreciate it. i don't have a machine shop, but i may end up having to make the parts myself. however, if i can find them, it would save me a ton of time and troubles

thanks!

Welcome to the Barrel nut

Numrich arms? Looks like they're out of stock on the yoke but they do have the block! Maybe a Western Field or Wards version would use a similar yoke?

Maybe even a pump shotgun would use a suitable clamp like that?

Here's one from a J.C. Higgins M10 B/A shotgun that might do until you (ever) found the right one. Just a thought.
