Not a manual trans guy, so bear with me. I have 2 here, they came to me in Borg-Warner boxes but the rivets say 'Beck & Borg' and the part numbers appear to be different. One is stamped GM7832, dated '69, other is GM8947, looks to be dated '68. They are 10.4", with 1 1/8" 10-spline centers. Found zero online on those B&B part numbers, but guy I got them from had a '63 4-spd Corvette. Centerforce's clutch discs that match those dimensions (and match the part numbers on the boxes: 383271) are for '63-71 327s / 350s, and '67-77 3-spd units. Asking $150 for the pair. In central NJ, would prefer not to ship.
If they’d work in my Muncie 21 I could use them if anyone can clarify for two low info manual transmission guys if these will work in a M-20 or M-21 behind a 3:64 geared 455 car. In line for a bit if someone can help us figure it out
Clutch disc's don't know what kind of cars they are in. There are 10 1/2" and 11". Two splines- course and fine. Course is 10, fine is 26.
Beck and Borg merged with Warner Gear and became Borg Warner, so a lot of parts sold by Borg Warner shortly (a few years of stock) after, would have B&B stampings, screen and paint an packaged in BW packaging. (back in the day of ample stock of parts, boxes and such already bought and paid for when companies merged or changed names)
