In the past I've seen a part # for tubular UCA's from either UB machine or stockcarproducts.com which are a bolt on for the 12" B-body disc brake conversion, but in my searches haven't been able to find it.

Anyone off hand have any info?

TIA, Kevin graemlins/thumbsup.gif

Kevin,this may be the #s you are looking for.
19-0908-6R & 19-0928-6L if not try
www.ubmachine.com. (http://www.ubmachine.com.) I talked to them a couple weeks
ago about these arms,they have screw in balljoints
which,if I understood correctly would require
reaming the spindle.But they also said they could
fab whatever a person wanted,like plates for bolt
on joints.
hope this helps,
Malcolm
