Is the front bracket for the bar there or just the two studs sticking through the floor?

I don't think powerglide cars got the bar.

No indication it ever had the bar.

Looked on camaros.org when I first saw the pictures.

CRG says brackets were installed on cars that never got the bars. Many of the glide cars being among them.

I doubt if this car ever had the bracket.

Charley, my '67 RS SS (350) with a powerglide looks exactly like yours regarding the radius rod brackets. The 2nd design axle bracket welded to the axle and no bracket installed on the underside of floor, just the 2 bolts coming thru the floor and of course no radius rod. My car is an 01D Norwood car.

CRG has seen quite a few of these cars with no bar and no front bracket and it was obvious neither were ever there.

That pic showing the crack is hopefully one of the freeze plugs and not the block. :eek:

I see liquid oozing out of what looks like a void/crack. Bottom right picture post #19

Definitely the freeze plug
