Hi, anyone have a parts breakdown for a 71 39d ? I am redoing the wood and the forearm barrel band does'nt have a screw head. I am hoping it is a pin but cant find any info or parts breakdown for a D , with my luck the screw head is broken off. I also may have a extra d forearm as i bought two too pick from. I think they are NOS. When I figure out how to post pics I will post one of the d.
