[QUOTE="ET43, post: 24334, member: 62"] The dimensions of the base of the FT170 can be worked out by looking at your pillion plates. The triangle has three holes in it, 1, the swing arm spindle, 2, the bottom forward hole of the pillion plate, and 3, the hole in the middle of the pillion plate. The last two are 3/8". The conical centre is usually tapped 3/4 x 20tpi cycle thread, but I have seen items specifically for Steib, 18 x 1.5mm pitch. The conical portion is scarfed away to clear the swing arm nut. Somne had the part number on them.some did not. Some were cast in bronze, but most were a ?? stamping. Cheers, ET43 [/QUOTE]
