I don't think cutting a hole in the frame is the answer, I believe if it did occur, the best response is to drill out the hole in the frame and weld a nut into place in the hole. This would give much more meat for the bolt to grab onto from then on...as long as the welder didn't blow out the frame in the area during the process.
I just don't have the free time to take care of an incidental such as this should it occur before June 5th. As much as I would like to have it on, I don't think it's the right move for me.
Too many other things occupying my limited free time between now and then.
But please...continue badgering me into it...it shows me that you all care and only want my car to be as fast as it can be!! lol...
