Hi . can someone out there give me the diamensions of the lower threaded portion of chief frame forging at the axel stay threads . Seems to be 24 t.p.i. but clamped area is so distorted no sure of true i.d. Do not have acess to threaded portion of axel stay to measure. Need to know tap size and major and minor diameters. Also-Where can i access chief frame measurements ???
Will appreciate any help,yours,Ben
