Prohibit a floater for safty conserns??? That is one of the reasons for a floater. If a axle brakes the wheel still stays on the car.Have u ever seen a 10bolt chevy lose an axle(C-clip)? I've seen them go over the catch fence wheel tire and axle. Very dangerous. At the last track I raced at the promoter finlly got smart after a near fatal axle loss and made floaters leagle and rear discs manditory in an atempt to reduce the amount of lost wheels and axles.
Good luck with the ear surch. You may have to bite the bullet and run in 2nd gear (3sp) to get the final drive u need.
