Anyone used a rebuilder who can correctly curve and rebush and restore an original distributor? Another way of asking this is who is the Pirkle or Jerry luck of distributors?

Hi-Tech Innovations of Panorama City, FL, phone number 813-942-4003 or 800-777-1818. Hi-Tech is one of the few, if not the only, distributor rebuilder capable of installing distributor bushings and JIG-BORING them to perfect alignment, as the factory originally did.
Hi-Tech is also one of the few which tranfers and re-brazes your distributor mainshaft "auto cam" (the cam-like device on the top) if mainshaft replacement is necessary. This is necessary if your original engine centrifugal advance characteristics are to be maintained; there are a VAST ARRAY of different "auto cams" and these cams, in combination with advance springs, advance weights, and distributor vacuum control account for virtually ALL of the differences between different Corvette distributor part numbers. Most replacement main shafts utilize a "universal" auto cam. With this, distributors will need to be "re-curved".
However, if you use a distributor with the original "auto cam", original or exact replacement centrifugal advance weights, original or exact replacement centrifugal advance springs, and original or exact replacement vacuum control, your distributor will have the EXACT original advance characteristics. Under such circumstances, "re-curving" will only be necessary if you want a DIFFERENT THAN ORIGINAL advance configuration. I recommend the ORIGINAL ADVANCE CONFIGURATION. GM went to a lot of effort and expense to engineer and tailor these advance characteristics to a particular engine. Then, they inventoried a vast array of distributor part numbers and parts for many years so that owners could maintain the original distributor advance characteristics which, as I mentioned, was essentially the only difference between the vast array of point-style distributors available. Otherwise, they could have just inventoried a "one-size-fits-all" SERVICE replacement distributor and drastically reduced their parts inventory requirements. In fact, that's what you get today if you purchase a "reproduction" distributor.
About 10 or 15 years ago GM shut down the distributor production line at the Anderson, IN Delco Remy parts operation. Virtually no parts for these distributors are manufactured by GM anymore and the only parts available from GM are point sets, rotor, and condensor. Even these are not the same as the original parts but are, I believe, manufactured by "outside vendors" to GM in contrast to the original Delco-Remy components manufactured in Anderson, IN or Flint, MI.
Hi-Tech Innovations reproduces some of the distributor components and also manufactures the needle bearing, tach drive cross gear/adapter assemblies. As far as I know, no one reproduces the vast array of original "auto cams" or the distributor breaker point cam.In Appreciation of John Hinckley -

Hi Tech is about 1/2 hour away and have done work on the collection cars. All work has been reported to be of the finest quality, at reasonable prices. They will rework my distributor this spring.
