Seats for a 55

Does anybody know what the best seats to use in a 55 belair would be (besides original). I have a full front and back seat in the car out of a 60 somthing buick or somthing, they fit fine But the rats have pee peed in the inside of the seats. I ripped all the (1969) carpet out and took the back seat out. Since nobody does upholstry work around here I thought of finding a buick roadmaster or somthing with leather seats and see if they would work.
Wish it was as easy as that, someone just telling me to get the seats from a 19XX XXXX and that be it but i am sure it will need some fabricating to make it work whatever seats I go with.
