Hello,

I did a little digging on here, but could not find a thread that discussed how to identify which Perfect Circle Cruise Control units were used during which years. I have one I am trying to pinpoint what it came off of. If anyone has any suggestions or knows of a thread I overlooked that discusses this, please let me know.

I can add that it does have a tag, like a carb tag, which says Perfect Circle 73025028 if that tells anybody a way to identify it.

Thanks for the help,

Josh

I believe those numbers are serial numbers, not part numbers. It would be easier to identify if you have the red sticker with the Chrysler part number on it. It would help if you posted some pictures. But the sequence number corresponds to either 1960 or 1961. I would guess probably 1960, but if you post pictures we may be able to tell the difference - especially if you have some of the mounting brackets with it. When you go to use this, it's the mounting brackets & cables that are more specific to the vehicle that you want to use it on.

The numbers from my auto pilot units, combined with Sven's are:
73004197_____1886084 '58-'59 Chrysler
73006848_____1886084 '58-'59 Chrysler
73012344_____1886084 '58-'59 Chrysler
73014490_____1972446 '60 Chrysler
73025028_____Yours?
73032022_____2257989 '61 Chrysler
13C-014878_____2257989 '62 Chrysler

Hi Josh, I can confirm that ALL 1958-1961 cruise control/AP "brains" started with the numbers 73 followed by 6 additional numbers which were stamped on the aluminum trim tag attached. This number was never stamped anywhere on the casing.

So, they were not specific for any individual year until these numbers started to change beginning in 1962.

I am able to repair/restore/refurbish most of these old brains depending upon the severity of internal damage over the years in storage. I have lots of spare internal components.

Cheers,
