Resource so I can find factory part numbers?

[FSHTAIL]

Where do you go to find factory part numbers for the parts on our cars?   

I feel like a bother asking for part numbers or where to get things and I'm wondering where everyone finds part numbers?
Is there some website where I can put my year, make, model in it and it reads like Rockauto so I can find OEM Chrysler part number?
Can anyone point me in the right direction?   

Thanks..

There are factory parts manuals in our Resources section.

Thats great!     thank you..

I was able to find a Mopar OEM fan shroud for a little bit more than the OER Taiwan stuff 
Thanks again..

Just a caveat. The factory part number could be used for many years and not change even though a part could change or be upgraded. So not necessarily the same part as you have even though the part number could be the same.

On a related note, are their any replacements to Lightningjar?  Someone else picked up that service and that seems to have gone to?  It was a very handy utility for doing quick online lookups.
