you can probably use a 02-4668 only a little shorter, even if you put a rubber bump stop on the bottom bracket to lift it up if needed
the part you want is 4-1/16" long and the 02-4668 is 3-7/8" so 3/16" shorter less than 1/2 a cm
bloody williams too many designers some the metal part is longer and some the black plastic is shorter
i have put at least 6 different one in a row and they are all only a fraction of a difference
