The front end is from T.C.I & the rear is stock mono leaf 10 bolt posi 3.55 gears and a set of cal tracs.The front is droped 3.5" as well.
Are you running the cal tracs with mono leaf springs? Don't know much about them but I need to install something to eliminate axle wrap on my 63 Acadian with 3.55 stock posi and mono springs.
I also have a new to me, 63 Nova SS just in from California that I will be installing a complete 64 SS drivetrain in with a 4 spd and stock posi/ 3.08 gears.
