I have contacted all of the below with no luck!

Brownels
Ruger
Gunpartscorp
Numich
Midwayusa
Jack1st
Trackofthewolf
And a few pawn shops out west that get them in regularly I think my best bet is if someone has had one and converted it to the modern sling swivels and kept the old swivels. If anyone knows someone who may have them or another site to try let me know!

Thanks in advance!
