OK - I'm confused ( at least more than normal when dealing with the Italian way of thinking). Does anyone know what I should be using as a parts manual for the Santamonica? I believe that apart from the brakes & wheels it is the same as the Laguna Seca - does this sound right? If so, where would I find the details for the brakes (these have the black P432 calipers with factory braided lines - unlike any of the others from what I can determine. In particular I'm chasing part numbers for these).

I once saw a photocopy of the Santamonica parts book on ebay and I stupidly didn't buy it thinking I'd wait for an original. Well I've never even seen another photocopy; but at least I know they are out there.

The front brake calipers are the same as on the 1988 851, and so probably the same as some other Ducati models. They come up often enough on ebay.

For the '88 851, the part numbers are 61040031A(left), 61040041A(right)

Apart from the wheels and brake calipers/hoses, the LS and SM were only cosmetically different; as you have noted.

Thanks mate. I've actually found a source & ordered a new Laguna Seca parts manual - should help a little. The rear hugger is one of my biggest concerns (mine's been modified).
