A Guide to Locating Factory Parts

Most owners of older cars have reached the point where they may need to get a replacement part, but either no one seems to have it, or stores have generic parts that might or might not fit.

It helps to remember that almost every Chrysler made part has a part number on it. Types of part numbers include:

  • camshaft part number#######--A seven digit part number usually starting with the digit 4 or 5. These are usually found on every part.
  • XX-##XXX--A seven code combo where the X’s represent letters and the # numbers. These may be fonund on interior trim items.
  • ##-###-####--These are book part numbers. They can be found on Chrysler printed materials. (The Mopar Performance catalog has 7 digit part number, this may be the only exception)

Now that I have a part number, where do I order it?

Your dealer can order it. If you know the part name and not the number, they may look at you funny, and you would have little chance to actually getting that part. But with your part number in hand, you have the power to actually get what you want.

tablesI don’t live by a dealer, [or I don’t want to pay their inflated prices,] where can I order it online?

There are dealers who sell online [see the Allpar online-dealer comparison]. [Typically they charge 25% off list, while some local dealers multiply list prices by two or more. However, they also add shipping charges, usually in excess of actual shipping costs, and have high restock fees for returns.]

Where can a I search for more dealers that may have it (can’t order online)?

You can search for dealers that may or may not have an online order form for your part at

Which websites accept which part number?

Most online dealers accept the XX-##XXX series code [editor’s update: go to the OEM/replacement parts page since they many dealers sell Mopar add-ons and the two systems are usually separate]. They also accept the seven digit number codes. If they don’t have it listed then you will have to call or e-mail them with the description of the manual or part number you need.

What if I want a decal whose part number wasn’t on the decal at all?

You search at www.arizonaparts.com for your part number (or call / speak to a local dealer). Still don’t like the price? You can cross reference their part numbers with the other sites listed above.

My part number looks like something you haven’t described, what’s wrong?

ignitionSometimes part numbers may look like #######AA [or AB, etc — the letters indicate a revision, and you may actually want a different, newer part; see the next section.]
The sites listed above will also find these part numbers.

Two letters after the seven digit part number that means it has gone through a revision; often, a revised part is better.

Eight-digit part numbers are often key-related such as blanks and transmitters, along with refrigerant oil as well.

Part numbers with letters in front often describe what they are, such as WB###### for a wiper blade or B###### for a belt. Sometimes they seem to be there just to confuse you.

What if my part number is not listed in any of the above databases?

Often Chrysler updates their part numbers. Check to see if the system says the ####### has been superseded by #######. Use the latter number in all databases.

What if my part number is not visible?

Go to PartsVoice.com or RockAuto.com to see if they have it in their database.


What if I don’t want to buy at a dealer but instead at a local parts store. I don’t care if it may look different, I just want it to suit my needs.

www.autozone.com and www.napaonline.com have part number translators. For cross-referencing, AC-Delco is excellent, as is Rock Auto. (“Factory” replacement parts are sometimes made to a higher standard, with better testing than some aftermarket parts. Critical suspension parts may be best obtained from dealers. [In some cases, there can be numerous shock absorbers or other parts from Chrysler, with a single aftermarket substitute part, which means that the aftermarket supplier is not tuning for each vehicle or setup.])

What kinds of parts can I get with part numbers?

You can get NOS (New Old Stock) items, such as original carpets; rare things such as a Chrysler Maserati TC training video for Betamax; jacks, carpets, seats, decals, labels, and rare accessories. Without these part numbers the chances of finding the above would be slim to none. You can make sure you are getting the correct part.

How do you know so much about part numbers?

I don’t work for any dealer, so this is just what I learned by searching myself. I search so much that I have a part number list just for my Omni. (Link broken)

Webmaster note: There are parts replacement guides, formerly in book form, then on CD/DVD. Wrecking yards often have parts interchange books, especially for body parts.
