    Power door lock relay help

    So I got myself a new AC Delco power door lock relay and the terminals are labeled 1-5, not the more familiar 80’s numbers. My harness connectors do not fit on this relay. Fine, I will cut them and just use individual connections. Can anyone help me to decipher what the numbers mean?

    Too much tire?

    What are you gonna do for wheels? 6 lug vs 8 lug. Have you priced a GM Dana 60, oh in the last 5 years or so? What traction device if any is in the rear?

    Issue after crossover steering installation

    I agree with a pump issue, low psi or gpm. Also to note, crossover steering will apply more lateral stress to the frame. If not already I would plate the frame and install the triangulation brace. You can drill out the threads in the steering box and use a larger bolts with stover nuts. It...

    "new" 350

    I “borrowed” it from my dad. He used to run a hydraulic repair shop and whenever they rebuilt an old Hein-Werner floor jack they would shoot it with this paint.

    Best budget lift

    Budget is subjective and will differ for each person. What is your budget? Do you already have wheels and tires? Why dual stabilizer?

    ‘83 K5: Confusion with ordering the right grill. Please help!

    The 83-84 grille is the same mounting as the 85+. The only difference should be the color. The core support is the same.

    K5 Frame Crack Honest Opinion

    You absolutely want to install the bolt in brace. It’s not difficult to install, and you can at this point loctite the steering gearbox bolts. A lot of cracked frames are the result of loose steering gear bolts. The bolt in brace will stiffen the area and you will feel it through the steering...

    Firewall circuit breaker

    Yup. Very common especially in the 4X4 and off-road community. Get a quality unit. As an example, https://www.mouser.com/new/littelfuse/littelfuse-zcase-fuses/?srsltid=AfmBOopqRxWVPqvgIIRdjGBNxbC7HnpVgqGP1qUsHB52FfjDN-QjkGkT

    Stock. If blackout you need to do something with the bumper and side mirrors, a satin finish over the shine.

    Should I go POSI???

    You say that you have a K series truck. If money is an issue, I would advise skipping a rear locking device and spending that money to have the front gears done as well. Having both front and rear drive is superior to just a locked/posi rear drive.

    This can't be good....

    GM did the math on running power through the switches. We all know that doing relays is the proper thing, which GM didn’t do on our trucks. So I don’t follow all GM engineering feats. Installing a midi fuse would be no more effort than installing a fusible link would be. Whichever method a...

    This can't be good....

    You are aware of time delayed fuses? Much easier to change a fuse over a fusible link. Diffusion pill technology is a method used primarily in electrical fuses to create a predictable, time-delayed circuit protection, particularly for high-current applications like automotive batteries and...
