Triumph GT6 Mk2 (2.0 Litre)  (1998cc)     (1968- 70) 

Check you still have the correct engine fitted - Eng Prefix No/ KC, KD, KE, KF.

These are +005 size. 

(** Not for any GT6 Mk1 before Eng. No/  KC5000 / KD5000 because the tabs on the shells are different **)

Before you buy this you need to find out / understand the following -

1) These are +005 size - Find out what size you need.

2) Check your Engine Number against the above, it's just below the rear most Spark Plug - Triumph's often have other engines fitted.
