Hi Rick and welcome to the forum. You have at least 3 good options:
1. Bolt it. That will keep your old drums going for awhile longer.
2. Reverse the drums. they are symmetrical and interchangeable. Your new #5 postiion was your old #2 position, probably untouched and like new. You can also add the bolts to prevent crankshaft flexing. You can even re-decal the drums for about a dime each.
3. Upgrade your Drive. This involves new drums and cables. Check your prices first. While you're at it, I would recommend upgrading to the V-2 sprocket and threaded mast. Both upgrades are much more durable.
Of course check out your warranty option with your dealer. If nothing else, maybe he can work with you on the upgrade parts.
Using the search function and FAQ you can find specific procedures as applicable.
