Quick z bar help

My super bee with a built 440 and race clutch used to do that. Got so bad it would eat the clutch disc in no time. Pulled the transmission and found a crack all the way across the trans tunnel, every time I pushed in the clutch the whole body would flex. shoulda put frame connectors in I guess. oh..and it would shatter the bushings as well. race clutches should have the whole pedal linkage reinforced including the Zbar mount on the frame
