Wilwood conversion problem

kit # 140-11022 is for 9" drum spindles. I have a numbers matching 318 - it's my understanding that all V8's came with 10" drums (the 9 " drums were only used on the /6's) plus I measured my drums and (unless I'm a total moron and measured wrong) they're 10". That's why I got the 10" kit (140-11023). But it doesn't fit my 14" wheels, and I just came up empty on a set of BBP rallyes I was hoping to get (off Craigslist) - the hub snout fit and the bolt pattern lined up, but there wasn't enough room for the caliper. My kit also comes with rotors that are .81" THK x 1.00" DIA (part # 160-5840).

I think kit # 2712 is for a drag racing set up.
