Clutch disk

["Stinocher, Bryan D." <bdstinocher@sewsus.com>]

Okay, here's one that I'm hoping somebody out there knows.

I have a TR250 with a transmission number of CD 21489, and then below that 7
L  69. I want to order the clutch disk to replace, but don't want to take
the transmission casing off just yet if I don't have to. My question is: can
you tell by the number above if that is a Borg & Beck clutch, or a Laycock?
The transmission has not been off before, so it will be as originally
installed. 

Any comments?

Thanks.
