Hey Man I saw your Signature and noticed you had a T56 Magnum. Did you go with the hydruallic clutch system or mech linkage? I have basically the exact same thing as you 71 Chevelle 496 t56 magnum 12bolt (needs gears). My problem is the collar they sent me for the input shaft made the throwout bearing bind. Just wondering if you had any problems with yours. Also is 6th gear street friendly? I am thinking with the .50 overdrive I can run some steep gears like 4.56/4.88 and not have any problems. Thanks man for any advice or help.
