Well let's start with a casualty report. Thurs. angle grinder died bought new cheap one (with the abuse they get from me good ones don't last much longer). Fri. belt sander blew a bearing, fixed it with parts from broken angle grinder. Sun. melted hole in air hose will fix at work.
With everything going wrong I was still able to get my removable backbone finished and in the car. 12 bolts, tight fit, told ya I could it. I don't think I need to worry about another cross member with that cage bolted to the frame. Kind of ties the rear suspension together also should cut down on twist as well.
