128 Coupe 1290cc Type 128AC.000
I would guess that the X19 1300 128AS.000 cam would be the same as the 128 coupe / rally (24/68 64/28 9.75mm) but it's duration is listed differently due to the different check clearance specified (0.60/0.65mm compared to 0.50mm)

128 Rally 1290cc Type 128AR.000
I really need to get hold of a "Specification and Features" for an X1/9 1500 1979 -1982 euro / UK carb engine (138AS.000) to confirm the camshaft lift and duration figures quoted by Haynes... but perhaps the Euro spec 1500 cam isn't "the best" of the standard bunch, for total duration anyway....
