My basement bathroom has an old American Standard toilet and it works great and is yellow enlongated bowl which matches the yellow tile. The problem is the old plastic seat cracked and broke I looked for replacement seats but the bolt pattern in back is wider than now standard 5-1/2 inches my toilet is 9-7/8 inches wide. I don't want to replace the whole toilet just for a broken seat. my house was built in mid 60's I assume it's that old maybe somebody out there has encountered this problem thanks in advance for any help.
