If the clamp and boot aren't loosey/goosey, I'd just run it and not be concerned. I think a lot of them that failed were just from yanking on the handle like an idiot. And if you smoke the top end someday, so what, then's when it's time for the p&c upgrade.
It isn't that big of a deal to finagle a band clamp on without taking everything apart, trick is to find the right clamp, needs to be narrower than the typical ones. Harbor freight sells those little assortment kits, up until about a year ago they had the narrow type but now they're all wide. Could get them on sale for like 3 bucks and they had 5 or 6 of the right size in there. I bought a bunch but have used all of them. Wish I bought more.
Can't recall the details but the tab on the stock clamp can be cut off in place (exacto/dykes/whatever) then just insert the end of the worm/band clamp in and push it/bend it 'till it comes back 'round, join the ends and tighten...
Can also use a big honkin' cable tie...
