A Little Bit About Us

Hiltop Auto Parts began in 1990 in St. Louis, MO. We bought our first obsolete inventory that year. Since then we have purchased inventories from over 80 Chrysler-Plymouth & Dodge dealers in over 20 states. We have also purchased many inventories that were already in private hands. We currently have over 100,000 parts on hand from fenders down to fasteners. We also buy inventories of NOS parts including Mopar, GM, Delco, Ford, and aftermarket lines such as Moog, Everco, Stant and many others.

We have sold a countless number of auto parts to thousands of satisfied customers through our eBay store. As a Top-Rated Seller, we have earned over 16,000 positive comments from satisfied customers, and that number keeps growing. Our reputation is built on honesty, strong communication with customers, and our ability to ship quickly. Today, we hope to reach out to more people and continue satisfying our customers through our website’s online shop.

NOS Versus Reproduction

I have received a lot of messages from buyers about reproduction parts they have purchased. To a person they have been disappointed with their parts. I find this especially with electrical items! All I can say on the subject is that Chrysler has gotten loose with their licensing of reproduction parts. At one point a friend of mine reproduced the deck lid medallion for 1966-7 Dodge Chargers some 30 years ago. It took him 2 years and over $5000.00 in fees to Chrysler. Of course that was the OLD Chrysler Corporation. Now I find that very few repro parts are licensed by Mother Mopar. Most if not all of the reproduction stuff in the market today comes from the far east [China, Vietnam, etc.]  which speaks to it’s quality and faithfulness to the original item. The old phrase “NOS is best” has never been more true.

Using the Website

The home page of my site has a search box. This can be used a number of ways. If you know the Chrysler part number you need then you can enter it directly in the search box. You can also search by year, make & models. For example “1965 Plymouth Fury” when searched will bring up all parts currently on the site that will fit that model. If searching earlier pre 1960 models I would stick with a simpler description such as “1937 Dodge” or “1955 Chrysler” instead of including the full model name. 

If purchasing a item and a shipping quote is desired then simply put the item in the cart and go to checkout. All shipping choices and costs will be displayed. If you don’t like the costs simply remove the item from the cart. No problem.  If purchasing multiples of the same item OR a number of items keep in mind that the site does not combine shipping. Any excess shipping will be refunded upon shipment and notification. I ALWAYS show the shipping amounts on my USPS labels so you will ALWAYS know you are being treated fairly when it comes to shipping costs. You will also ALWAYS get a personal e-mail with your tracking information in addition to a notice from USPS. 

Understanding Some Terms Used On the Site;

NOS- New Old Stock. A NEW original part that would have been used on the assembly line when your vehicle was produced. MAY OR MAY NOT come in Chrysler packaging. Chrysler DID NOT make any parts that went into their cars. All came from outside LICENSED vendors. For example, Chrysler at various times used Bendix, Wagner & Raybestos for various brake parts. Among the electrical suppliers were Autolite, Fasco, Standard Ignition & Prestolite among others. I can tell you that I will NOT sell a part as NOS unless it comes in factory [Mopar] packaging OR it carries the correct casting of service number on the part itself.

NORS- New Old Replacement Stock. A NEW part that is produced by a aftermarket manufacturer intended to be a service replacement for the part specified. If they are USA manufactured parts they will certified as SAE [Society of Automotive Engineers] parts. This means they will meet or surpass all the specifications that the car companies published for their suppliers. 

SUPERCEDES- Chrysler would often update a part number to a new number. This would usually occur when there was a vendor change. For example, The original part number for a 1967-9 non tilt turn signal switch was 2771802. In 1968 this same switch was superceded to part number 2857241 and then in 1969 to 2947801. They are all basically the same but I’m guessing that the manufacturer was changed at lease once if not twice. It might have gone from Autolite to Prestolite to Standard Ignition. Only Mopar knows. When using a superceded number I am ALWAYS going by official CHRYSLER information as stated in their supercede books that were sent to dealerships back in the day.

MASTER PACK- Over the years I have had the opportunity to purchase some items directly from the Mopar suppliers. Some of these items came in what was called “Master Packs” that would have been shipped to Chrysler for them to put into their own brand packaging. It’s a original NOS part without it’s box is what it boils down to. 

Growing Our Inventory

We are always looking for parts to add to our inventory. If you have parts to sell, please contact us. If you are within 500 miles of St. Louis, we will travel to your location if you have a large enough quantity. We are also interested in aftermarket obsolete inventories from regular auto parts stores and distributors.

We have recently purchased a new 7,000 square foot distribution/warehouse facility that will allow us to list more items and also expand inventory and product lines. In our new facility, we will continue to offer 24 to 48 hour shipping on all of our store & website inventory.

Today, we are working harder than ever to make all of our parts available on our website. With over 25,000 part numbers of NOS Mopar and another 15,000 assorted Ford, GM, and aftermarket parts it will take some time to list it all. If you do not see the part you are looking for, please contact us by email AT hiltopap@aol.com or visit our eBay store to see if we have the parts you need.
