Roll Bar Attachment

[landy]

My '72 came with a four-point roll bar. The two back mounting pads are on top of the inner fender wells. The two front mounting pads are just behind the front seats. Seems like it would be best to have a metal plate underneath the body sheet metal rather than attaching the mounting pads to just the sheet metal.

I realize it's no where near the strength or rigidity of having a roll bar attached to the frame, but this is proably better than nothing.

Thoughts?

Thanks.

Technically if the vehicle is equipped with a frame then certified roll cages are attached to the frame.

When a frame is not present, the sheetmetal has to be plated to pass tech.

Either way, something is better than nothing at all for a street car.

My blazer has what is considered the factory Hinkle bar that was offered back then and is simply bolted right to the floor as you describe with no reinforcement of the sheetmetal. (Just the stock 4"x4" square piece attached to the bar itself)

I personally was never worried about making it better and suspect it might be better than nothing in the event of a roll over (I doubt it would support the full weight of the vehicle however), but there is definately room for improvement if you feel so inclined.
