got bored and decided to build the roll bar .made the hoop first ,then the cross bar and the down bars. i fish mouthed the ends so they would fit up tight to the hoop. just about broke my wrist with the notching tool when the saw hooked up and the half inch drill spun me around. broke all the teeth off the hole saw and bent it .i got lucky. any way , i tack welded all the pieces together inside the car to make sure every thing fit the way it was supposed to, then took it back out to weld . put it back in place all welded up and welded it in the car. it cost me a whole $29 .00 lets see you buy a roll bar for that .
