63 slant 6 904 transmission seal and o ring question

orieellys has national o-rings for sale each behind the counter, you just have to ask them because there idiots, and yes i use to work there lol.
I already have a full set of sae o-rings on order. Decided to buy a full kit as I use them frequently. Gave up going to parts stores to ask for individual parts as all the old school guys seem to be gone and all the new replacements have never turned a wrench. For most of the new guys if it doesn't show it on the screen it doesn't exist.
