Just adding a recommendation to the list here. I used my Proto 90t flex 1/4" you're asking about yesterday on a Miata rear shock top hat nut where my Snap-On extra-long 1/4 72t had too much arc swing to grab the next tooth. The extra teeth in the Proto worked perfectly.
FWIW, the best prices I've found are at circlesupply.com. I liked the first short 1/4 so much I bought 3 more (so far!) from them.
