1925-36 Chevrolet Parts, Reproduction, New Old Stock, or New Old Replacement Stock

This page is set up for 1916-1936 Chevy parts that are hard to find and are normally worn out on these old cars. There are 7 sections to look at including: STARTING SYSTEM, Cooling System, FUEL SYSTEM, ENGINE PARTS, OIL PUMP, TRANSMISSION and DRIVE LINE,

These are NOT the replacement parts that are kicked out of a factory (who knows where) because it was cheaper to make that way. These are the parts that are made to fit and with superior materials. The new old stock/ new old replacement stock (NOS/NORS) was made when there was pride in workmanship, usually in the USA. Where some of the reproduction parts haven't been USA made, we try our best to assure that they meet the same or better standards as original. 


 NOTE: =should be in stock and available to ship within 1-2 business days.

          =normally not in stock or limited supply; This may take up to 3-6 weeks for delivery.

                              Email for more information.

If you order a part and then decide to cancel the order without contacting us, you will be subject to a 5% refund fee as our merchant account / PayPal no longer returns fees charged to us and to cover paperwork. It is strongly suggested that you contact us before ordering if you are unsure about shipping times, correct part or any other problem that may come up.


Our brochure for these 1916-36 Chevy items is now back and covers more parts than it used to. Please send a request to bob@marxparts.com if you would like one. Our old brochure form no longer works so put brochure in the subject line and your address in the content of the e-mail.
