K member swap and upgrades. Bergman pins

Well I just installed these with delrin bushings from Peter Bergman but do not I repeat do not torque to the specs specifically told to me by peter he said 145 to 150ft.lbs of torque the shop did this and pulled the pin through the fing k member not pulled thru but enough to make a perfect crack in the shape of the pin I called Peter and I had him on speaker phone told him what happened and he said that's not possible he said most shops can't get them that tight because they will start to spin if we get them to 105ft.lbs is good enough I then sent him pictures of the k member he told me that he could tell someone had did a really hairy messed up welding on the k member we thought the same after looking at it but after I finally found another k member and my old 1 was taken out it was not previously welded it was from when I brushed on por 15 and it had ran and looked like a bunch of hairy stuff so do not torque to his specs torque to 120ft.lbs and everything will tighten up 3000 dollars later on me will save you the same headache
