How long are FT33 (Pivot Bearing Spindle) and H25/5ASS (Series D rear axle)? I'm after two axles which are 11" (280 mm) long and have a diameter of 1/2". They should have 7/8" of thread on one end and 1" of thread on the other (1/2" BSF Thread). I have an example axle here which was bought a few years ago but unsure of its part number. It may possibly be either FT33 or H25/5ASS. Any help would be greatly appreciated. Thank you.
