1972 Dodge Colt

Hi,
Like your car and wish I could have found it first. Lol. I am buying a stock ‘71 Colt, which should be home soon. I am a huge Don Hardy fan and have owned several V8 Vegas with all of his parts on them. I should be able to copy Hardy’s chassis with some help from a local race car shop. Could you tell me the hub flange to hub flange measurement on your Dana 60? I see you are going with a smaller slick on the rear. Is this because of wheel choice/availability?
Thx,
Tim
