The catalog carries it under 40-0325, with 40-325 as an older form of the same number. Our records show it turning up across a couple of seasons around 1969-1970, but that's catalog appearance data, not a fitment guarantee for any specific model.
Because the dimension range is narrow and specific, this is the kind of spacer where measuring what comes off your crankcase matters before ordering a replacement. Call the shop if you want to confirm you've got the right one before you buy.
