I have a late 81 Subaru Brat that has rear shocks with a stem on top that protrudes into the bed with caps I cannot source these shocks anywhere does anyone know where I might be able to find shocks that fit I’ve been searching for months also can’t find a shifter linkage shaft seal anywhere everything calls for the 7000 seal but it’s way too big any help would be appreciated 

Sounds like someone installed Monroe or Gabriel air shocks. You can replace them with like or the correct shocks, Rockauto has the stock ones - https://www.rockauto.com/en/catalog/subaru,1981,brat,1.8l+h4,1267657,suspension,shock+absorber,7556

As for the shaft seal, you may need to remove it to get the numbers from it so it can be matched

Ah, Rockauto also has the seal!
