I re-tested the gauges again using Patrick's suggestion. I meant to post a close up of the labeled gauge yesterday but forgot to. (picture 1)

Picture 2 is the overall view of the connections.

Picture 3 is a close up of the connections with the extra, stock 90 OHM resistor added.

Picture 4 is the readout on an old gauge I have

Picture 5 is of the gauge in my good cluster.

Instructions are the same as before, just with the extra resistor added.....

Installed the headlight relays today. Pretty straight forward if you follow the instructions on the board. You can buy the kits from almost every truck parts supplier or put your own kit together from junk yard parts.

Below are the diagrams. First one is Chevy, second one is GMC

Picked up a 4.10 gear for the Dually HO72, to replace the 5.14. It should drop the RPM and help the mileage some. I need to get a new pinion seal for it.

The 4:10 will be a nice addition.

I am guessing 2200 RPM at 70MPH.

I've been working on the replacement 4.10 center section for the rear end. I not only had to replace the pinion seal but I also had to install a pinion seal repair sleeve. I could tell when I looked at it that the seal was going to need replaced. The yoke had a pretty good groove in it when I disassembled it. I filled it with JB Weld and installed the repair sleeve while the epoxy was still wet.

I only had to pull the axles out far enough to clear the center section when I removed it..

I had to figure out how to get the center section up in the air far enough to get the transmission jack under it so I put a piece of steel pipe across two of the frame cross members and put a rachet strap over the pipe and around the bottom of the center section. I just tightened the rachet strap up until the center section was high enough to get the jack under it. I cut the heads off of 2 bolts and screwed them into the housing to use as guide pins to locate the center section. (you can see one of them in the 8th picture) When I got it high enough I just slid it onto the pins and put the bolts in. Before I slid it all the way back I put some "Right Stuff" sealant on the gasket.

The rest of the pictures are the gasket, and specs on the gasket, seal, and repair sleeve.

The pinion seal and pinion repair sleeve were ordered from Rock Auto.

Nice work on the Rachet strap lifter device.

30 years ago, you would have done that differently?

You got that right. Now I have to use my brain more and my muscles (that I don't have) less....


I haven't checked my mileage yet but it dropped my RPM to about 1950 RPM @ 60 mph.
