Hello all! New member here. Just picked up a RF-31 on a really good deal. Looking to fabricate some small parts for my boat and do some gunsmithing work including completing some AR15 lowers. At any rate, I'm looking for the cross bolts that tighten the head to the column and prevent it from moving side to side. From what I can tell they appear to be 11/16"x6 bolts. It appears as though the previous owner used 5/8"x6 bolts and the hex pattern doesn't fit the hex pattern on the head so it causes the bolt to turn when I attempt to loosen or tighten from one side. I end up having to jam a screwdriver in there to secure the bolt head while I turn the other side...it's kind of a pain. I bought 3/4"x6 bolts and they're just a hair too big so I assume they are 11/16. I'm having a heck of a time locating these bolts...anyone have any idea where I can find these? No luck at HomeDepot, Fastenal, or Grainger. Thanks!
