Does anybody know of a thin walled 38mm (or 1 1/2") socket? All of mine are heavy wall impact style black sockets. I just need something thin walled or "normal" thickness. No torque requirement here at all, it's just a relativly light duty 3500 lb trailer axle castle nut inside a hub with very little clearance. If worst comes to worst, I'll mill a socket down on the outside, but if i can find a thin wall socket i'll just buy one... Thanks!
