There is a TD21 S1 parts book on ebay just now, that is very useful (essential really) for the exploded view drawings and part numbering. It ends tomorrow. The TD21 S1 owners manual is also available as a new reprint on ebay, not cheap at approx. GBP 24-00, but good quality and extremely useful with important data like wiring diagram, brake-servicing, timing, valve clearances, carb-settings etc. Also very useful for all 3 litre owners is the collection of works issued technical documents compiled by Nick Simpson, available from AOC. Hope this helps, Giles Lacey Posted by lacey giles 07/08/2014 11:29:16
