Key Cylinder In Column Won't Turn - Can't Start Truck

So I went to start my '77 K20 the other day. I haven't driven it much lately and it has just been sitting. When I went to start it, the key wouldn't rotate out of the Off position. It would freely rotate to the ACC position and the radio would come on. It feels like the cylinder would move, but the rod linking the cylinder to the ignition switch is bound up or something. It all worked fine the last time I drove it. Any suggestions? I know I probably have to lower the column, but maybe something simple I am not thinking about?

Sanding/buffing/polishing

June 30, 2025, 05:45:50 pm by whipper.snapper | Views: 41 | Comments: 0

Hey yall, I have a question regarding polishing my paint.

My process right now has been to Sand the little bit of orange peel that I have starting with 800 or 1000 and ending on 2000 or 3000ish.

Following the sanding I start with 3M perfect-it rubbing compound with a foam pad on a rotary polisher, and then finish it up with the 3M perfect-it machine polish.

The problem: there will still be scratches showing after using the rubbing compound, do I need a more aggressive cutting compound? Do I need to go higher in sandpaper grit? Or do I just need more elbow grease and do more rounds of rubbing compound?

Also, if y’all wanted to let me know what your favorite cutting/polishing compound is that would be great. This is my first time.

Thank you in advance!

Does anyone know part number for carrier bearing and rubber boot

Does anyone know what correct carrier bearing and whether there is an appropriate rubber boot?

I'm in the process of replacing the carrier bearing and it looks to me like there should be some sort of boot to cover the open spline.

The u-joints are spicer 1350 series (1.188 OD x 3.63 end to end) and the carrier bearing is 1.574 at the bearing with a 1.500 dia spline.

Its a 1979 K30 with SM465 transmission and a 454 that was swapped in, also its got 4.56 gears.

I'm going through the dana / spicer catalog and theres a handful of these (carrier bearing) that come up under style 15 with 1.574 ID, 6.62 bolts to mount and 2.25 dim from bottom to bearing center... but they have different front slinger / rear slinger. If those are the pieces on the end, then I want to replace them if I can.

Intermittent wipers not working on 83.

June 22, 2025, 12:03:45 pm by slideways | Views: 143 | Comments: 1

So finally getting some miles under this newly redone K10. I had to get a new wiper motor because the pump quit. I noticed that the wipers work fine on low/high but they dont work on intermittent. I assume that twisting the little knob is supposed to change the frequency of wipe? It doesnt seem to do anything. Is there a typical failure here?

Thanks

Ground connection on instrument cluster

June 20, 2025, 10:16:30 am by greenacres | Views: 368 | Comments: 7

I have been working on my 1979 Chevy K10. I have progressed to the point that I am ready to install the instrument cluster and dash. The ground wire that goes to the instrument cluster was missing when I got this truck back from the body shop, but I can easily make a new ground wire.

I have looked and looked and I can’t find anyplace on the instrument cluster to connect a ground wire. Can someone please tell me where the ground connection is on the back of the instrument cluster?

I don’t know if this makes any difference or not, but the body shop replaced the cab and I think it is from a 1977 C10. I don’t know which cab the instrument cluster is from, and I am not on speaking terms with that body shop.
