spindle question

66-72 Kelsey-Hayes disc setups mounted the calipers to the rear. That's the quickest and easiest way to determine which brake setup the customer has. Sounds like the parts guy ran across an irate customer who got the wrong parts and was trying to make sure it didn't happen to you. I would have asked the same question if you had come to my store wanting disc brake parts for a 68 Dart. In future, leave the year of the car out of it if you are wanting parts for a conversion, and ask for the year that the parts in question came from. This store sounds like a keeper.
