the hardest part of rekeying one of these old locks to match a key is going to be prying the bezel off without damaging it. Then you just mix, match and delete the tumblers until you have something that works. if you have a spare lock or two you can probably fully match the key you have, there are usually only 3 or 4 tumbler heights to choose from

I've had several vehicles over the years with only 2 or 3 or even zero of the original 4 or 5 tumblers. if it looks like a lock and works like a lock it is a lock. Easier to pick than originally intended but thieves don't pick locks, they find stuff unlocked or brute force an entry
