Question for Alan 71
Alan I have a 72 small block convertible that I am getting ready to rebuild the upper and lower control arms on. The control arms upper and lower has different style shafts in them. One side has round shafts and the other has square. I know the drivers side front of the car has had damage and I am assuming that the A-Arms were replaced at that time. Would you have info on the correct shape shaft that came with this car?
Thanks
Mike

Hi Mike,
These are the original cross-shafts on my 71.
I would expect the shafts for your 72 to be the same configuration.
They all have 2 flat surfaces, and rounded surfaces.
The flat surfaces on the upper shafts are less pronounced, but still obvious.
The flat surfaces on the lower shafts are more pronounced.
The shafts on the upper arms can be turned… it doesn't matter which of the 2 flat surfaces faces the frame mount.
The shafts for the lower arms have an 'up' and 'down' which determines how the shaft should be seated against the crossmember.
Regards,
Alan

Hi Mike,
I believe I'd begin by calling Bair's Corvettes in Linesville, Pa. 16424.
They have a good selection of suspension parts and hardware.
