Bolt in frame connectors

According to @Mattax , to run auto cross class I am thinking of, they cant be welded in. Bolted in only.
Hey Tim,
Welded to the front and rear subframes is OK for ESP & SM now. It wasn't when I first did it. :BangHead:
But only two welded points. A third attachment is allowed, but it must be bolted.

Mopar performance ones are in my car now. I'm going to go to 2x2 tubing and trim down the height just where it goes under the rear footwell. Soon, very soon.
