Hi,

 

Recently installed a pypes 2.5 exhaust system and did not realize till the car was on the ground that the rubber line on the rear axle is touching the exhaust pipe. In order to remedy this, since my exhaust is fully welded, I plan to move the rubber hose with the T-block to clear the exhaust pipe.

 

I was wondering if anyone knew offhand what size brake line go from the the T-block to the drums?

Also, what size is the nut fitting that go into the T-block and drums?  

The car is an 81, but the rear is from a 76 firebird.

3/16" brake tubing. You'll need 3/8" wrench.
