My "kit" was drop shipped from Classic Performance but bought through another vendor. The vendor who I bought the parts through did not mention the wheel issue and since I was unaware of CPP I didn't see their website.
In their defense, CPP does mention that "Stock drum brake wheels MAY not work with disk brake conversions" then they continue by stating "Before installing this kit make sure your wheels fit" on the instruction sheet. In other words after you have bought the kit and installed it bringing this discussion back to the shipping/restocking expense.
The part that Jim Carter sells is useless in my case. In order to get my stock wheels to clear the calipers would take a spacer at least an inch thick.
What I should have known from experience I don't have isn't the issue here. Vendors omitting critical information regarding the usability of expensive parts is my point.
