    Rotted out EGR diaphram frame

    Actually getting ready to do the same. High rise (stock) cast iron 4.3 Qjet intake. Had to pull the a/c compressor and mounts, air pump tubing and fitting, and a couple dozen vacuum lines/wires, to remove a valve cover. First time off in 40 years. Jeg’s stand alone hei distributor, no esc...

    Struggling with my 700R4

    In my case, definitely . 1979 block/heads. Unknown year redrilled tbi mid-rise manifold. Everything else is stock 1992 parts on the engine. Have to use the “universal” (fits -nothing- correctly) tv cable. And like clockwork, every 8 months lunches reverse and 4th, snaps the flexplate, and gets...

    Crossmember?

    Just buy a new harness from EZ or Rebel wiring. Less than $300, gets you a new fusebox (cigarette pack sized), all new plugs, deletes the fusible links, every wire is fully labeled, no corrosion under the insulation… A couple pack of plain fittings, some heat shrink tubing… Buy once, cry once...

    Anyone bought the AMD premium / chrome grill?

    Now that you’ve shown it, I want it, and the matching bumper. My originally red/white 85 is named “Ralph”, after Ralph “Sonny” Barger. An 85 to 81 conversion would be most appropriate…

    Search for a spare 15-inch wheel or two

    When I needed new steelies for a 56 210 Delray, Parisienne and similar BOPS plus standard Caprice “old people got to church cars” were 5 on 4.75” bolt pattern. Just like S10s. Real (rwd) Cads depended on model, could be either. GM “does” stand for “General Maybem” after all. Rear mount...

    Search for a spare 15-inch wheel or two

    My 85 C10 swb, 4.3/400, shipped with 15x6 van rally wheels and P205/75r15s. Has run 215/75s and 235/75s. Currently has Dextero DAT1 P235/75r15 XLs on the rear, going with 215/75 or 205/70 XL up front. Lightest duty suspension ever offered, 3+1 rear springs, 6 cylinder front coils. Rear flip...

    Hood scoop

    Functional or decorative? I’m actually quite partial to the hood blister you’d find on 60s Ford factory drag cars. Or the Ram Air dual scoop style used on Buicks/Pontiacs from the late 60s. For function, open up the 2nd core support inlet, run a dual snorkel air cleaner. Cowl hoods and such...

    1981 K30 cab and chassis dually wheel width. They are 16"

    I daily your truck’s “younger brother”, a 99 K3500 c&c dually. Anything over an LT235/85r16 you will need rear wheel spacers. I run 235/85s up front, 265/75s out back, as both are 31.6-31.7 inches tall. To stay in that range with period correct tires, you would be looking at a Deestone 503 in...

    255/60/15 vs 275/60/15

    Width is determined by your wheels… 2wd rally wheels were 15x 6, 7 or 8 inch. My 85 swb shipped with 15x6 van rally wheels and P205/75r15s. Had P215/75s on all 4 corners for years, and then LT235/75s. Since it is now a toy, right down to having a permanent “antique” plate… P215/70s and P235/75...

    Dually Rims

    I don’t know about other owners, but stock steel inners, 2” spacers, then the alloys on my K3500. On a stock 14b ff. Seems to work okay, not like anybody can see the inners courtesy of the mudflaps.

    Dually Rims

    If you run alloys, the shanked lug nuts and washers make the lug centric. But, you have to retorque them every couple days for 2-3 WEEKS before they settle in and stay tight. Tire size does play a role, as does tread style. A 31” mudder will basically shake the entire front end apart on an ifs...

    1978 vs. 1988-1994 steering wheel bolt pattern

    They are the same at least mid-60s through 2000 gmt400 carry over models. That is how you properly dispose of 95+ driver side airbags. My 85 is getting a 92 steering wheel, my 99 K3500 is getting the 85 steering wheel.

    Dodge Parts??? Behind seat tray

    Why not just fiberglass the stock cardboard piece? That’s what I’m doing to my 85 swb. Get it back roughly in shape, coat it with resin. Press the glass cloth, not chopped mat, into the resin, work out any air bubbles (white spots). Then topcoat with more resin until the cloth is fully wet. If...

    LED exterior light conversion! not going well :(

    They work great, have them in the cab top lights of my 1 ton flatbed dually, as well as the front corner lights (gmt400 K3500). I also run led tails (full panel), bed markers and headlight inserts on that same truck. Tails and bed markers are from “Hazard Fraught”, work perfectly.

    Quadrajet Mystery and questions

    Same carb I have been fighting with… 1985 with the electric thing. Except mine is so worn out that it “sweats” gas…

    Newer Model Bed

    There have been a few on Memphis area FB marketplace the past couple months. Was looking at a complete but not running 82 standard cab C30 dually that needed some body work. Beds kept popping up. Decided that my 4wd 1t dually was sufficient.

    3 minute battery life…?

    Positive cable end was cold, negative cable end was sizzling hot.

    3 minute battery life…?

    Yes, turns freely with the plugs out. Can lay under it and turn it via the crankshaft pulley. Air pump belt is removed.

    3 minute battery life…?

    Stock heater core, aluminum/plastic radiator. Just like the one that popped an end tank seam. 2017ish radiator hoses, heater hoses might be originals.

    Best tires

    Not sure, I have to dig a bit deeper. You “can” order tires from a shop in Juarez, have them shipped here, but it puts them in Coker price range, plus import duties.

    Will load it into the crusher and push the button myself before it gets any kind of fuel injected engine…

    3 minute battery life…?

    The battery ends of both cables are clean, shiny, and bare. I usually run a Group 78, and use charging lugs as the battery cable bolts. Much easier to clup an in bed sprayer pump to than normal side terminal bolts. Now, tbh, I cannot remember when I last changed out the negative cable, the one...

    3 minute battery life…?

    Has been “off” since my father in law had the coolant changed in 2013. No heat, radiator popped an end tank seam, waterpump siezed. Got the radiator and waterpump swapped, I did the radiator, farm co-op the waterpump. And he then filled it, again, with Dexcool… Truck takes green coolant. No...

    3 minute battery life…?

    Started fine in 2023. Ran fine, just way down on power and leaking like the Exxon Valdez. Tune up was last month. Today was the first time I tried starting it in about 4 months. Been working on the chassis.
