Yes they did make them in different sizes, I know they made some massive 11 or 10 1/2" ones + the standard 8 1/2 or 9" ones + they have different types from different times early 80s, late 80s & 90s. The 90s ones had an ovel crossbar, where the 80s ones had a round crossbar.
Im sure someone can explaine this with some pic's
