Technical Service Bulletins
During the TR7 and TR8 production run, plus for some time after production ceased, British Leyland (later Jaguar Rover Triumph) provided Technical Service Bulletins (TSBs) to their dealers.  They aren't just a Wedge phenomenon - TSBs could be issued for any marque and model.  The majority were technical in nature, but some are purely administrative.

Through 1979, TSBs numbers include a character to divide them into component sections (e.g. engine, chassis).  Starting in 1980 the component indicator was dropped.  Here is a more detailed explanation of TSB numbers.   

Below are links to the TSBs TWOA has to date that are pertinent to the TR7 and TR8.  We will publish others as they become available to us, so be sure to check back from time to time.

NOTE - There are some publications that weren't officially listed as TSBs, but were TSB-like in the information they provided.  An example is the 1978 Pre-Delivery Inspection Emission Controls Related Checks.  A year later the 1979 version of that document was issued as a TSB.  So  you will find some non-TSB documents included in these lists.
