Competition Engineering bars on Ford 9" Problem

I am installing a 9" in my 70 and trying to reuse the comp eng bars with J bolts on it. My problem is the old 8.5" 10 bolt had 3" axle tubes on it and the new 9" has 3.25" tubes on it. My question is do they make j bolts for the 3.25" tubes or am I going to have to stick a set of 3.25" ubolts on it and forget about the j bolts?

I tossed the J-bolts after stripping the threads too many times. Car worked just fine without them---1.34 60 foot on 9" street tires

Thanks, will shelve the j bolts... will be happy with a 1.6 60 ft so this shouldn't be the limiting factor.
