K member swap and upgrades. Bergman pins

If the pivot pin fits tightly at the back of the tube
If i have play on the LCA side, what do you suggest? I have seen folks run weld around here, but I left it until I got my pivots. Now that I have them (the pivots) I know they are a smidge longer and I have a little length to play with. I did make a mistake by welding on the LCA side previously and am a little shy to mess with it (LCA side) but I am open to suggestion. the driver side is tight.....the drinkers side has 1/32"+ of play...on the LCA side. Also, when welding the front side washer on there, how did you locate it to be center? I feel like putting the whole deal together and in the car with the torsion bar in place I could make sure it was easy in/out?

Thanks for the help.

EDIT: I see you have welded the LCA side in your pic. so front and back ....correct? wait, I re read the post....just on the back side. copy that. I wont change my post as it may add light to the situation.
