1967 GMC 1 ton dually

[Rsuddeth]

I have been wanting an older truck for a long time. I wanted something a little heavier duty. Well I think I found it. The 305 V6 runs great, but the brakes don't do much. I will be making a plan/parts list on Saturday to start rebuilding those giant drum brakes. I am also looking forward to being part of this forum.

Cheaper to keep her! Have someone call you with an unbelievable deal on a Dually, then just deal with the *****ing and tell her how great a deal it was and you couldn't refuse it.

I have had little luck researching a CM3600. Anyone know the details?

I upgraded my 67 C30 to hydroboost front discs, and I would do it again every time. I bought a junked out 1975 C30 dually and stole the hydroboost system from it.

Awesome project! What's up with the spare glove box lid with speaker?

Shop for new, smaller trucks. Let sticker shock sink in. Find "screaming deal" on old dually. That might work.

And to the OP - great score!

[Rsuddeth]

That is the original glove box with all the numbers and options. Apparently someone cut a hole and stuck a speaker in it at one point in time.

my first 67 was a c10 the exact same color.

Definitely not trying to hijack your thread but I wanted to show you a pic of my 68 1 ton I am building.

I have a build thread call Meet Homer.

Once again I apologize, just wanted to share.

Looks great

[Rsuddeth]

Rear brake inspection. Pretty good lip on the drum but otherwise things aren't too bad. Definitely need wheel cylinders. Anyone see anything I should be worried about?

[Redline novdog]

You got heavy duty!! Nice truck. Welcome aboard. Looks like a good cleaning and brake rebuild to me. How do the bearing stubs look? I locked a bearing on a full floater axle, never could get it to seal,ended up replacing with a used 14 bolt. What rearend do you have there?

[Rsuddeth]

It is an H072 with a 4.57 ratio. The axle/bearing stub looks good though am a little concerned with the drums. Left one has a pretty good lip cut into it. I haven't looked at the other side yet.

[Redline novdog]

I don't know about that old of drums but the newer ones have a minimum dimension cast into the drum. Way cool problems, nice truck.

[Rsuddeth]

After a little reading, am I correct in assuming I can use a regular 80w90 gear lube for both the np435 Trans and the h072 rear end?

[Torpex]

I cant remember who I bought them from, but some outfit in California was where I bought 2 new, made in USA drums for my HO72. I pull a Horse Trailer with my C20 4x4 and I can say the brakes in this truck are absolutely outstanding. Manual brakes that respond like power brakes, wish the brakes on my K5 Blazer were this good..lol

Torpex, I think Centrix has them. I am not too concerned as I have some spares that came with the truck.

[Rsuddeth]

Should I replace or rebuild the wheel cylinders? Do they rebuild well or is it just better to replace?

[Cape Codder]

If the bore is pitted I would replace them. If not clean them up with a hone and rebuild. Make sure to get all the old fluid out of the system.

[Rsuddeth]

What about oil/lube for rear end and trans. Any suggestions?
