4wd spicer hub color

[724wd]

I have a question about 1971 and 1972 4wd short bed trucks. Was the color of the original Spicer hub turn outs made only in blue? I have been told blue was the only color in the 71 and 72 short bed 4wd. Also, would anyone know what that color of blue for the turn hubs is?

70 is red, 71-72 blue, 73-77(?) mustard yellow. As for the color blue we’ll i can’t answer that part they are just blue.

Thank you for the info. I had completely forgot about the yellow hubs being on the 73 and up trucks. Once I started paying attention I have noticed that some of the original hubs I've seen on trucks have faded, a couple that are all white, but still original. In fact I have 2 on my truck and want to get them back to blue. Just need to research how to do it. Thx. again.

yes, blue for you - and just to be clear for those that may ready this later - color of the hub has nothing to do with wheelbase. Same for short and long beds.

[724wd]

Thx. Jocko, I had seen a long bed 71 that had a blue hub but it seemed a much darker blue than the few I have seen on short beds, that could be for any number of reasons I guess, ( fading on some hubs or refurbished hubs, etc. )

Just one blue used for all K/5-K/10 and K/20 hubs. They are molded in color, so there is no paint color other than one that looks the same. Look at N.O.S. knob pictures and find a close color

Tim could you send that pic to Santa for me? I’ve had those listed on My Christmas list for years and he must not know what they look like. I still have yet to receive them, but am waiting patiently

Old thread, but always good discussions.

1968-1969 K10's/ 1969 K/5's used the red dials GM 3937068



1970-1972 K/5 / K10's used the blue dials GM 3979551



1973-1980 K/5 /K10's used mustard dials GM 6259019



1970- early 1971 K/20 used red dials



1971-1972 K/20 used blue dials 3995867



1973-early 1977 K20 used mustard dials 6259022

I don’t think that is correct, the closed knuckle axles (‘69 and before) used the hub lock aluminum dials as far as I’ve ever seen. Taking it a step further ford did use the red dials as well in the late 60’s-early 70’s.

That is an impressive collection.

[57taskforce]

Very Interesting no doubt about it. Anyone ever seen this in real life?? I’d love to learn more about it.

1969 Blazers used the open knuckle drum brake Dana 44 from what I have run across.

Here a 1968 K10:

[jerry moss]

in my experience 70 K series was the only year for open knuckle drum brakes, 69 and older was closed knuckle drum brakes. so were blazers different in 69 and got the open knuckle front before the K series trucks ? i've never owned a 69 blazer, only 71 and 72s but i've owned several 70 K series trucks with open knuckle /drum fronts and a few 69 K series trucks with closed knuckle/drum fronts.

[57taskforce]

Truthfully 69 open knuckle drum on a blazer wouldn’t totally surprise me, as it was the first year and only model in the 69 year to have the option of the 205. Everything else used the Rockwell until ‘70 when the rest of the K fleet started using the 205. If I’m not mistaken I’m pretty sure you could get a th350/205 in the 69 blazer as well. Again a 69 model year and k5 only combo, until ‘70. Truthfully I’m still quite skeptical of the 68 and earlier red dials and red dials on anything earlier than ‘70 save possibly the blazer. The reason I say this is because I’ve personally seen a bunch of pre ‘70 trucks with the early hub loks and never a single red dial on anything other than a ‘70. (Again blazer stuff is a bit more believable to me because of the aforementioned reasons)

I surely will research this in the coming days as I could definitely be wrong, no offense but one truck off of BAT doesn’t prove much to me when there is a ton of documentation on here that indicates other wise.

Not to say the GM partsbooks are gospel, but they are compelling...

Nice pictures, but without full information they don't necessarily represent 100% original equipment. I don't know about the '69 Blazers being open knuckle or why they would be different from trucks in '69. But, most definitely, all trucks from '69-back had the all metal lockout hubs. Those are also Spicer, therefore are listed as such in the GM parts books. I haven't checked my book, but I'd imagine those have a different part# from the '70-ups

Not sure of color but I have seen two variations in complete NOS Lockout sets I have had in the past. I am having some reproduced and will have them available near the end of the week.

I am doing 69-70 Red Half Ton & 71-72 Blue Half Ton

1968 half ton was red. Don't know the exact cutoff of the red half ton dials, but my March 1970 St. Louis Blazer always had the blue dials as verified by my father who put the first miles on it. I have personally owned it since 1987 when it had 50k miles on it and had bald original tires on it.

Seems at least according to torque king the open knuckle 69 blazer is quite possibly a reality, which I’m not totally surprised about as I said before. I’m still not sold on the dials on non K/5’s pre ‘70. It’s been a while since I’ve played with the aluminum dials but I seem to remember that they don’t directly interchange with the plastic dial hubs. someone correct me if I’m wrong. It’s been a decade or more since I’ve messed with the spicer hub loks.

I’m not surprised on your blazer having blue dials from the factory either. I’ve seen other original later model year 70’s that had blue dials in the past.

GM info has been posted. Pretty compelling info that the 10/68 parts book contradicts your statement.

I find it laughable that all of those 1968 trucks I located were converted over after the fact with red knobs.

We will agree to disagree.

[72ironmike]

JoesJunk had an original low mile 1971 with red dials. Our guess was they came from the factory that way.
