Hey sadly this is not something that's as easy as walking up to the parts counter and ordering,usually .
First off are any of yours salvageable for measurements? If so take them to your local autoparts and match them up.When I shop for fuses,I just go to the rack or bin and I don't ask for help,I just sit there and compare.Honestly I get my fuses for my early cars at Walmart,autozone,etc. I also make sure to buy several of them at a clip to have around for spares.
Another option would be If you happen to have a napa or a carquest near by,Id take a ride by one and have them check for you,those types of stores usually have a more diverse selection and workers who are more intersted in looking stuff up for people with old cars.
