Mk1 172 Exclusive
The top one
Both of those part numbers are vendor specific numbers. The actual Conti-Tech part number for the kit you want is CT977K1 between 2000 - 2001 and CT977K2 for vehicles 2001 onwards.
I've never fitted a K1 before so couldn't tell you the difference but I suspect it'll have the same belt, tensioner and idlers as the K2
I used the 30% discount code which I hope made it a good price!!wow that advert is wroooonnnnggg
ph1 was 00>01, ph2 was 01>05
Thats not a good price either
