This new long style adapter is ideal for use on engine swaps w/ the T-56 and other Late Model manual transmissions. This extra long bleeder screw (part # LS642001ERL) is 4.421" long and this extra length makes it easier to reach w/ a wrench inside the bell-housing. This bleeder screw has M10 x 1.5 threads, and has an -4 AN male flare that can be used w/ an AN hose to catch the fluid outside the bell-housing during the bleeding process.
