I'm getting tired of all the welding under the car... ugh
I've done more work under my car that most people we never see...
So all that welding and fabricating I was wondering about welding to the uni body frame rails. I remember back in the 90's they were made of high strength steel and you could plug weld on them but you would weaken the metal if you welded to much Have any idea on that MMP.
