Aux Rad Part Number Please

[Ivan Good]

Hi

Looks like I'm starting with an Weeping Aux Rad. I'm going to replace both at the same time, but getting conflicting part numbers (differing last letter of part number) What is the correct number please> The car is on a 56 plate, but sure that makes no odds.

Also pointers to best places to buy please.

Thanks

Ivan

Just checked my paperwork from when I replaced both Aux Rads, part number was A8E0 121 212
