K member swap and upgrades. Bergman pins

The first K I did I bought Firm Feels gusset kit, the second K I just made everything myself. The LCA pivot tube gussets are on the rear only, I actually used a heavy duty washer from the hardware store when I made that particular gusset. I think it was like a 1-1/8” washer? I just sized it so it fit around the outside of the pivot tube and then cut the washer to be even with the top of the K.

On the front side the pivot tube is welded to the inside of the K and the tube doesn’t protrude out. I know @Jim Lusk opens the K and welds those from the backside. I did not do that on mine, on a clean K you can see where the factory welds are, I drilled a couple holes through the K to the tube and did plug welds on the front.

If the pivot pin fits tightly at the back of the tube the side with the LCA should carry the majority of the load. And with that side welded solid the front shouldn’t go anywhere
