i had a buddy use a "mico-brake" he swiped off the 65 GMC tow truck we used at the body shop [68-72] because he couldn't afford a line lock. we replaced the one on the tow truck because it was leaking. my bud tore it apart and replaced a couple of o-rings to get it fixed. it worked like a four wheel line lock because his car had a fruit jar master. i think that car was a 65 impala with a 3speed on the floor.

my cousin sent me that exact add a day or two ago. this must the upcoming speed part trend !
