VINNY - you're not stupid, just not informed.
Its the fault of MB not to correctly inform you of the required part numbers. And in the first place, they should make universe parts where all MBs can use a common radiator.
That is what I find so frustrating sometimes when looking for a part. They look alike, but world apart because of one number ... e.g. 12602312065174 vs. 12602312065178.
I say this because I wanted a new VDO, and I thought all VDOs were alike - I mean, they look the same in size, colour and function. But no, they're different coz at the back of each has different sockets and pins.
Anyway, I wish you well in detecting this part.
Support FASTLANE. I would.
