Title: Postons GN 107 T cam specs
Post by: Turbodave on January 28 2012, 08:58:51 AM

Hello folks.  I recently acquired a new Postons GN 107 T cam, but without a card.  I've searched until blue in the face and have only found a couple of tid bits of contradictory information.

Anybody have an old cam card for one of these layiing around, or actually know the specs???

TIA!

Thanks a ton!  Sounds like a perfect cam to go into my numbers matching block that's getting slowly put back together.

It does sound like a great replacement cam!
