Disc spindles for my ’69 300

Going to do another project...drum to disc conversion on my '69 300. Currently reading the massive thread on the subject. Looks like 73 spindles may be the way to go? PM me if someone has spindles. Looks like that will be the hardest part to track down. May go for earlier style if I can source rotors at a decent price for the pre-73 spindles. Let me know. Thanks!
