The serial number for the box will have either TNN or HM around the edge of the bell housing, as distinct from the more usual 260 which will have NW, ANB or TNW. Cheers.

Paragon 14 Report post Posted June 18, 2014 The one manual car I have does not have the original gearbox in it. One spare gearbox I have is stamped ending NZ - any idea what that is ? Quote Share this post Link to post Share on other sites
