We had a discussion about this many years ago on the 428CJ site. We found a number of CJ C6s which "appeared" to be H servos all of which had cast iron tail shaft housings...including my KR vert that I've owned since '72, an original owner California Special 428 CJ, and a very low mileage original KR vert owned by Scott Fuller. It wasn't an early/late thing, because my KR is very early, and Scott Fuller's was very late. We found no explanation at the time, but based on the video it would seem likely that these are really R servos made with an H casting.
There was an old mechanic at the Ford dealer I worked for back in the day who used to say if you're working on a Chevy you just need to know what decade it was built in...if your're working on a Ford you need to know what year, what month, what day, what time, what plant, and what supplier, if you want to get the right part. I've come to know he was more right than I ever imagined at the time...
