Question about a trans I have.

I put five thin smooth .061 Red Eagles in every 727 now. Costs a little bit more but it's easy to do. With the drums that already have four, it goes right together with the stock thin steels. But there are some thicker steels out there that you usually can't use and get the clearance. If the drum has only three stock, then use a forward drum lower beveled pressure plate on top to fit five.
