The Lotus Grand Tourers

Just purchased a Excel and need a copy of the service notes, seem to be two different ones same ref number except one ends in j the other in z guessing it's release dates, which is most appropriate for a 1988 model. Thank you, going to be lots of questions over next few months.

One Lotus parts the first letter is the revision code (A=1st, B=2nd etc..) and the last letter is a supplier code used inside the factory.

http://www.thelotuscentreonline.co.uk/L ... vice-Notes is currently about the most cost-effective way of getting hold of the service notes by a legitimate route.

Not wanted as already have option to purchase just wondering what the difference was with one being a J at the end the other Z both start with A.
Thank you.

Check to see which one has the most comprehensive set of additional "Service Bulletins" included. These were issued by the factory after the service notes were produced. And make sure it has all of sections MA, MH and MF to get full coverage of the electrical system.
