These crush washers are the correct size for NA oil pans, all transmission drain plugs, 6-speed fill plugs and all differential drain and fill plugs. Well, all generations of Miatas, anyway.
They do not fit NB oil pans. 5-speed fill plugs do not use a washer.

This does not fit an nb1 trans fill plug, it's slightly too small.
Hi David, sorry for the confusion! You are correct - the fill plugs for the five speed transmissions do not use these crush washers because they have a tapered thread (no crush washer necessary to seal properly). Our product description didn't reflect this specific bit of info before you made your purchase, but we've updated the listing to reflect this information. We also see that you purchased several of these crush washers, so please send us an email if you won't be able to use them so that we can help you out with an alternative solution.
Satisfied with the ordering process and the items received.
Used on my ND for transmission fill/drain and diff fill/drain
Great price and they fit engine oil drain , transmission drain and diff drain and fill on my NA 6
Needed 2 crush washers ASAP. Local Car parts store wanted $2.50 each! Bought them, then ordered 12 from FM for future Oil/Trans/Diff fluid changes.
Great doing business with FM over the last 12 years.
