    Thanks for the help! I believe we are looking at a switch pitch converter here. Correct?

    I didn't want to list this until I made sure it was what I thought it was. Purchased this new for the Reynolds GS.

    Jim Weise can confirm, but it sure looks like one from the picture.

    Variable Pitch- Looking down the hub, you see two bushings with a space in between, and then the stator splines. This is true of both the 12" and 13" VP converters, and no other converter will look like this.. This is positive ID!

    IIRC I sent a KB switch pitch convertor to you for the 65 Reynolds project.

    Thanks Nick, is that what I have in the first picture above? Did the 13" converters only have the weld spots?

    Ted,
    Is that the blue converter picture above. That one came from Lee Myles in West Roxbury, MA

    I really don't know. JW would be the guy to ask.

    I have two converters, one in the Reynolds Gran Sport and the one pictured above.

    Ted,
    I believe the KB converter is in the Reynolds GS. I'll be removing that from the car next month.
    I'll be happy to send that back if you like. Has 5 miles on it.

    yes, the indicator is the two bushings with the space in between them, and then the splines. All you see down the hub of a fixed pitch converter is splines.

    Jim,

    It's been many years since we spoke about this, but I'm bringing it up again for others.

    Please forgive me if I'm wrong, but there were variable pitch converters advertised and sold by Poston Enterprises and Jim Burek which had some shoddy workmanship, and big shortcuts to achieving higher stall speeds.

    I still have one buried in my basement, and after learning about the shortcuts I'd not put one in my car.

    There was a poor fellow on a Cadillac forum if I remember right, he had a massive failure and shared the photos.

    Anyway! Buyer beware. Many folks have had no trouble, but...

    And we know THEY weren't doing the converter mods, that kind of work is farmed out. BUT, in the end the seller is responsible for the supplier's work.

    Devon,
    I understand what you're saying about their converters. Short cuts were one of the reasons for their demise.
    The converter above (blue) was rebuilt by Transtar Industries in 2008. I spoke to them this morning and they
    still have the converter number in their records/archives. They told me they hold on to this info for tracking
    quality and insurance purposes.
    Appreciate your input.

    No worries Jack,

    Just pointing out an ancient memory that popped into my head reading this!

    I suppose, the gap between the 2 bushings is where the extra oil passage in the input
    shaft opens up, with fluid to control the pitch change. Bruce Roe
