Did you see the note on the end of first post?? (as I cant tell if you mean 'there are 2 types'!! or the diffrence between the types I've mentioned at end of first post!)
Not being funny wiv ya Ray, just unsure!
Well I cant see the pictures you posted as im in work.
There are two types of Cambelt kits iirc. The pulleys are different, ones plane rollers and ones rollers with lips, mines a early engine and its using the ones with lips. One early one and one late one. Not sure why your book shows 3 procedures tho. Probs something someone like Geff can tell you.
When I spoke to Autovaux about cambelt kits last year they said the bracket the middle pulley bolts to also differs but I'm not sure how.
I had to take a photo of mine and send it to them, as my block has no engine number.
