My '98 Expy came with the 17" alloy rims. I would rather get a set of the chrome 17" rims that I've seen, but can only find information online about the chrome rims coming in 16". Is this right? Will the later model Expy's with 17" chrome rims fit on my truck?

And - more importantly, where can I find a set of the stock chrome 17" rims without breaking the bank?
