    Whip antenna for CB on a Suburban

    On a somewhat related subject: my wife and I like to go to flea markets, pawn shops and swap meets. One of the pawn shops I frequent had a brand new Solarcon A99 antenna, still in the box. I paid like 50 bucks for it. Anyway, I had it in the garage for several weeks, hidden behind my car on the...

    Whip antenna for CB on a Suburban

    On my truck, I ran the coax from the center of the roof down the center of the rear window. From there is zip tied to the floor until it reached the bolt in shifter plate for these trucks if it was equipped with the 6 speed manual trans. I drilled the hole thru that, I figured there are millions...

    Whip antenna for CB on a Suburban

    I use to be big into radio when I was a kid. My fascination started when dad bought a Buick Electra with factory am/fm and built in CB. I was probably 6 or 7 years old. I have had a radio in every truck I have owned. Back when I had disposable income, I use to snowmobile a lot. We used Cb to...

    Need help wiring power windows and door locks 83 K1500

    It helps being cheap! I grew up watching Scotty on Star Trek (the Miracle Worker!) and McGuyver. It ain’t broke if they can fix it! It’s been very beneficial to have access to a couple salvage yards that allow me to roam around looking at cars. I have found it’s sometimes easier to adapt...

    Need help wiring power windows and door locks 83 K1500

    GM used a screwed up complicated power door lock system in those years. It’s hard to explain, but pushing a button on one side uses the other side to complete the signal path to the relay. Entirely to many wires, too many failure points. My fix: use a common door lock relay from a later...

    Smoking Ground Wire

    I bet you will find either a loose ground wire, or bad corrosion inside the insulation of the heavy ground wire. Since the main ground wire is compromised, the smaller ground wire is trying to pick up the slack. The starter is pulling far more current than the wire can handle, causing the...

    Mechanical fuel pump return line

    Yep, the lower the pressure (or vaccum) the lower the boiling point.

    Old school garage door opener remote

    That’s exactly what I’m planning to do. A block of wood cut to fit in the opener pocket, with a push button placed in the correct spot should work. I figured there were lots of those remotes out there, why engineer something that is easy to find? How wrong I was!!! Apparently, there is a bit...

    1976 Chevyvan G30 stiff accelerator pedal

    Make sure the cable isn’t twisted or kinked, look for obvious damage. Unhook the throttle from the carb, does the carb throttle plates move freely? If not, try moving the throttle with it unhooked. Find out why the throttle is stiff. Having a pedal that is hard to push is an inconvenience...

    Mechanical fuel pump return line

    The return setup would be preferred with today’s lousy gas. The 3 port pumps have a tiny orifice in the return fitting, basically a controlled internal leak. It’s constantly circulating fuel back to the tank which keeps the fuel and pump cool. The other advantage is hot restart. Imagine it’s a...

    Odd Cooling System issue

    Did the same thing on my first car (64 nova). I was 15, that’s a mistake you hopefully only make once!!

    1986 sbc th350 ran dry on ATF :o

    If you can build an engine, you can do a TH350. With the possibile exception of a Chrysler 727 or 904 transmission, it’s probably the easiest to work on. Work slowly, work cleanly, don’t force anything, check your clearances, and air check each assembly as you go.

    Looking for 13.5v-13.8v voltage regulator

    The resting voltage of a fully charged battery is around 12.6-12.8. To the best of my knowledge, regulators have always been calibrated to put the charging system voltage around 14.2-14.5. I have no clue how you could cheat that, other than converting to an older externally regulated alternator...

    Headlights not working

    Make sure he plugged in the dimmer switch. That’s the only thing I can think of that would prevent the lights from working in either low or high beam.

    Replacing turn signal switch in 75 High Sierra

    If you’re comfortable with removing the steering wheel, once that’s off you need to buy or rent a lock plate depressor. I’m sure you can find a dozen YouTube videos, while it’s not difficult it does take a little patience. Be gentle with the snap ring that retains the lock plate, it’s pretty...

    Rally wheel colors?

    Crap, I forgot I started this thread!! Right now the truck is kinda Frankensteined, the front is the factory brown. The bed is a darker brown that the newer Chevy trucks use.

    Is this part of the evap system?

    That plugs into the cruise servo.

    Any explicit help on removing AC components and keeping heat?

    That’s all that’s needed. Technically, the air comes from the cowl area, goes down to the blower motor, the motor forces air thru the rectangular box, and then the various doors direct air thru the heater core, and to the various vents/outlets. You will still need the vacuum line and vacuum...

    Rally wheel colors?

    Decisions Decisions! I’m trying to decide what color to paint the rally wheels on my 81 GMC. I had originally planned to just go back with the factory Argent silver, but my son suggested black. I immediately dismissed his thoughts as foolish and juvenile, but now I’m reconsidering. I’d hate to...

    700r4 slipping in cold weather

    What did the spacer plate look like? Anytime I have a 700 or 4L60E apart, I plan on replacing the plate. The check balls beat the plate pretty badly, sometimes they get do worn out the ball actually gets stuck in the plate. If it still slips, it’s going to get worse. As nick suggested, a...

    Firewall Plug Pin Identification

    Series 59 male terminals. American Autowire carries them, I think the Electrical Depot and Mosier has them as well. Those are both main power feeds from the heavy red wires that go down to the starter. inspect your headlight plugs, series 59 female are in those sockets. Now would be the time...

    Need help with my 700r4 TTC wiring harness

    This is the method I used to wire the TCC on my 81 GMC. The only difference, I used a time delay relay I bought from Amazon. It was about 15 bucks, and has a 10 second delay. https://www.hotrod.com/how-to/hot-rod-rescue-lockup-700-r4-torque-converter-without-computer/ If you use a standard...

    Speedo with trip odometer?

    So I need to narrow my search to a 88-89 suburban with trip odometer? That shouldn’t be hard to find!! The smart, quick, and easy thing to do would be to just get a replacement speedo that works and is quiet. What fun would that be??

    Speedo with trip odometer?

    I don’t normally drive my truck in the winter, but I needed to today. While the engine started instantly in the 8 degree weather, the rest of the truck wasn’t happy! Problem #1: the blower motor screams when it’s cold. Fortunately, that didn’t last long. Problem number 2: the speedometer...

    Power window stuck halfway

    You’re the exception to the rule. The same rule that says fuel pumps never fail when the tank is empty, only immediately after filling the tank.
