Super A rear weight bolts

Any idea on the length of these? I believe one side is longer than the other due to the wheel dish being a weight itself and being pretty think itself.

Thinking I had seen this somewhere before and not being able to lay hands on where I put it I looked on Rudi's server

Anyone have a good supplier for these size carriage bolts? I have not found them anywhere locally.

Try the Fastenal web site.

Terry, try Industrial Screw in Baton Rouge. I got the carrage head bolt for my weights from them, they had the size and length in stock.
