KEVIN,i just took my 727 apart,my aluminum drum was worn alittle, i am replacing my drum with a billet steel one and while my drum is apart i am changing to a BOLT IN SPRAG, for $175.00 its a no brainer.
without a bolt in sprag, its a matter of time before that tranny lets loose and goes through your floor cutting off dads leg.
with the power you making now, you have to really upgrade your parts correctly to avoid an accident that can be prevented, build it right the 1st time, it will save you money and aggravation later on.
