Mark: Mike McClusky at McClusky Ltd can probably answer your question. I installed a pair of Wilwood stock car calipers on my 289 cobra.... using the stock rotors. The only modification that I had to make was to split the calipers and mill the mating surfaces to work with the stock thickness rotors. It appears that you are using stock uprights... so I think that the solution should be pretty straight forward. If you want, I can give Mike a call to see what he recommends.
