Hi Everyone...
I ran into an issue with one of my spindles on my 1960 Chevy C10. I understand the spindle is the same on both sides (drive vs passenger), but does anyone know if the spindle changed between the years (1960 to 1966)? I found one for sale that states it is for a 1960 to 62 and then I found another one from a 1964. Looking at their pictures, they look to be the same, but was hoping someone knew for sure.
I did find out that the hubs from 1962 to 1968 trucks can fit onto the 1960 spindle (Thank you red7218!!!) leading me to believe the 1964 spindle is the same as the 1960 spindle.
Any help would be greatly appreciated... ...Russ
P.S. I am not interested in upgrading to disc brakes or lowered spindles. The truck is 95% stock besides tires etc and I want to keep it that way.

As I remember, the bearings and hubs are the same 60-66. The nut that holds the wheel cylinder has different threads in my 1963 compared to my 1965 IIRC. ** Just curious if you might be the guy who bought a fleetside rear bumper from me about 8-10 years ago?**

Hey Lugnutz...
The bearings and hubs are different because the 1960 and 61 hubs used ball-bearings (which require much more maintenance) and the 62 and above use roller bearings. So, the 60 to 61 hubs have a bigger diameter hub for the ball bearings to fit and have different spindle nuts and washers along with a different cap than the 62 and above (with smaller diameter hubs, washer and cap).
My problem is the spindles. I have read they have different part numbers between the years, but I was hoping to hear from someone who can tell me from experience.
Sorry, I am not the guy who bought the fleetside fenders... I have 2 step-sides and 1 dump truck... no fleetsides....
Thanks, Russ

Thanks, Russ Russ, Ahhh! I seem to learn some thing new all the time about these trucks. I did not know the differences that you mentioned about the front wheel bearings. I sold a fleet side rear bumper (not fenders) to a guy in New York. To the best of my memory, he lived on Long Island, but I could be wrong about that. I put the 1966 fleet side rear bumper up for sale locally on craigslist. Apparently photos from craigslist appear on websearch images. He was looking for a 1960s fleet side rear bumper with nice patina and was casually viewing images on websearch. He clicked on the image of my bumper and it led him to my craigslist ad here in Columbia, SC. He called me and asked if I was willing to ship it. I was surprised that someone was willing to pay for shipping all the way to New York. We made the deal and I believe he’s a happy customer.

Hey BC59...
Yes, that is my goal... to upgrade to hub's that use roller bearings instead of ball bearings. It is because of the ball bearings that I need to replace one of the spindles which need to be done before tackling the hubs... Can I ask what year hubs you are using on your 1960 c10 spindles? I understand you can use 62 to 68 hubs.
Thanks, Russ

Ask old parts man, he said "double duty", step vans & such.

Thank you. That solves a mystery I've had for years. I see it on Vin tags and I see it in parts catalogs. My take is when on the top of a Vin tag (DD) it was for the Delivery Date to be stamped by the dealer. Most were not stamped. The paper work was suffice.
When in a parts catalog it means, what Chevy called, a Dubl Duti. Package Delivery style truck and etc. Thanks again.
