    Anyone have flywheel/pressure plate dimensions?

    I have a new flywheel for the 331, but I do not know if it is for a 10" or a 10.5" clutch.  Anyone have a known flywheel or pressure plate they can measure the pressure plate bolt pattern for me?  I need to order a clutch but want to avoid the trial and error thing.

    Re: Anyone have flywheel/pressure plate dimensions?

    If I remember correctly, the PP bolt patten was the same for both the 10" and 10.5".  I suggest checking with the manufacture.

    What's your C measurement? Nothing on my setup measures 10 or 10.5".

    I've got a McLeod 10.5" clutch.



    My A measurement is 10-3/8".
    My B measurement is 5-11/16".

    Re: Anyone have flywheel/pressure plate dimensions?

    Thanks, BB.  I will compare to mine.  Hoping mine is 10.5"

    I know the 10.5" and 10" require different bolt patterns.  If they didn't, everybody would be sticking 10.5" clutches in their early Stangs that came with 10".

    Re: Anyone have flywheel/pressure plate dimensions?

    Anyone else have dimensions?  Double redundancy on checking always helps!

    Like an old guy at work used to say...
    Measure it with a micrometer.
    Mark it with a grease pencil.
    Cut it with an axe.
    It will fit perfect!

    More than 1” difference in the B dimension between two 10.5” clutches???

    Re: Anyone have flywheel/pressure plate dimensions?

    Mine measures same as Bearing Bob’s dimensions. Turns out the box still had the part number. Ram 1527 which says 10.5” in Summit catalog.

    Thanks, guys!

    I ordered a stock replacement clutch from Summit.  I got the clutch kit, release arm and bolt/dowel kit for $151.
    Now to design that 69-70 cable clutch kit I have been trying to get around to for twenty years!
