My manifold heat shield is ratting bad. I've found various part numbers. Does anyone now why there's 3 different numbers for the same shield on this page?

It looks like part number 12578647 is applicable to the 2007, 3.7 engine.

OK, thanks I can see the difference now, '40 - '06, '07- '08, and '09 - '12

I'll contact 1BADI5

Thanks for your help. I don't know why I didn't see it before.
