Thanks for the heads up. This was a better price than Tim was going to be able to get from his aftermarket clip supplier. I ordered 200 for about $55 US with shipping from the UK. Much more reasonable than Chrysler's $450.00.Check for proper fit but they all look the same. I searched Ducato 2537 one site had a fitment chart can't find now though.
You can check the compatibility of the clip here there are 17 pages. I'm sure Pete knows what he needs.Be careful - that listing says for '01 to '06 the Promaster is based on '06 to '14 in Europe. It's most likely possible they are the same clips but for $55 you want to be sure! I'm assuming your clips look the same as the ones in the listing but it wouldn't hurt to double check with the seller.
