Andy and 3B

Thanks for the info.
I removed the rear axle brake line and it is 1/4", this is why I'm looking for wheel cylinder line threads of 7/16-20. Even though RockAuto's catalog shows them, they won't give me the info
on the line threads over the phone. I know I can always run a reducer to match my line up with the cylinders but wanted to avoid the extra joint.

Thanks again
Jeff
