I decided last week-end to tackle the cambelt change on my Omega Elite estate (3.0 X30XE).
I got the locking tool hired from autovaux for a small fee with the purchase of an SKF timig belt kit (VKMA05501) and water pump.
I follow the DVD all the way and everything is going well (having a spare TV in the garage helps).
I lock all the cams, remove the original belt, change the plate that has 2 pulleys on it, change the water pump, and when I go to put my shiny new belt, I realise I can't align the markings on the belt with cams 3 and 4 (they are 5-6 teeth out) .
Looking at that new belt, it wears the number 05500, which is the belt that goes with the early engine kit (same number of teeth though).
I call autovaux to complain I've got the wrong belt supplied with the kit and they say that since the belts have the same number of teeth, SKF does not bother making 2 different ones for each kit. They offer to send me free of charge a genuine GM belt they have in stock.
I get home tonight, open the parcel and the genuine belt is for an early engine, the markings are identical to the SKF belt

Now, can I get a belt for a late engine with the right markings on it (e.g. from Vauxhall)?
Is there any way I can fit the belt ignoring the markings?
Any help appreciated, I'm getting desperate.
