ThreeQuarter's 1968 C10 Build Thread

[ThreeQuarter]

I've been noticing a vibration that coincided with road speed (not engine speed) but the frequency was higher than tires/wheels/brakes would normally produce. I had been running the original driveshaft for the time being, so I decided it was time to replace it with all new parts. No dice.

I started looking into driveline angles and it turned out that my factory setup was pretty bad. All of the u-joint angles were around 2.5deg (reasonable), but the arrangement of the angles was not ideal. After some measuring, drawing, and calculating, I ordered 1/2" worth of transmission mount spacers, 4deg axle shims, and some new axle u-bolts (because I had cut my existing ones to exactly the right length). The results were very satisfying! That vibration is gone and I can ride easy now knowing my u-joints aren't aching.

Any updates on this beautiful truck?

Hey Chris, thanks for checking on me. I haven’t been on the board much lately because there hasn’t been a lot of work getting done on the ‘68. Been driving it some—just turned 5K miles on Monday, which is not as much as I intended to drive it. Still need to get HVAC installed. At some point I just gotta prioritize it and get it done!

Glad to hear that it's getting some drive time. I need to get mine our more now that we're back in Texas. Years ago I bought some original style base trim level black vinyl seat trim from SMS but haven't had the seat recovered yet. I probably should've let them make the cover. Yours turned out great! Excellent work on the painted pine bed floor. I almost never see anyone go that route. It makes me wish my truck had a wood bed to restore. To me, nothing looks better than one of those body colored wood bed floors.

Where did you get that vintage cruise control kit? I'll bet it makes longer drive much more enjoyable.

Can't say enough good things about your truck, just love what you've done with it.

Ben,
Good to hear from you. I hope you all are good!!!
Any of those tornados close to you?
I'm guessing you are still in Iowa?

Gorgeous....there are about a million words I could use, but gorgeous seems to cover it...
