    Is this a correct bracket?

    it looks like your return port on the Pump is correct for 78 but that looks like a later year bracket.

    Pulling Sucks--2001 Suburban 3/4 ton--6.0

    I agree with most of the suggestions here regarding tune up parts. When I first got my 05 2500hd, thing ran like a scalded dog. After several years started to loose a step. Did plugs and wires and got way better. Never threw codes. On a trans America drive lost the map sensor. Ok. Replaced that...

    No spark need help

    I can't help but notice the orientation of the new distributor is different from the old. Are you certain the rotor is pointing at the correct cap terminal and it's not out of time? Did you bring #1 to tdc on and install how'd that all go down? It might be firing but not at the right time to...

    truck runs hot

    I'd put it in the intake manifold if you have an empty (plugged) hole. In the thermostat housing it will only register true once the thermostat opens. If the thermostat fails to open you might not know it immediately. As an option you can drill a couple 1/8" holes in the thermostat to let...

    1977 C10 AC not working, solution suggestions

    Looks like that one that is bypassed is the thermostatic switch.

    Feels like front suspension 'bottoms out' over speed bumps.

    And those shocks are probably maxed out on length. Front blocks are a bozo-no-no, And are probably half the problem with your steering

    Battery negative ground question..... again, sorry !

    Looks like a perfectly good hole in the front of the driver side head.

    Where does negative battery cable ground wire attach?

    Here's the batt cable routing from 75. Note the headlight grounding screw location. That's where that broken one went.

    Wheels

    I have a set that look like that American Eagle 589s I think procomp has a similar. Series 89 or something like that Edit:::: I was wrong. Series 69. https://www.procompusa.com/product-skus/pro-comp-69-series-vintage-wheel-15x10-with-5-on-5-5-bolt-pattern-polished-1069-5185/

    Seriously bummed with this drivetrain setup right now :(

    Not sure if anyone mentioned this but in all reality you want the rear pinion pointed a couple degrees down from directly at the t case with a cv because youll get pinion climb under load. That way it'll be near zero under load.

    14 bolt brake drum question

    I swapped from 11 to 13 on mine. Only issues I ran into were differences in e-brake cable attachment and I needed longer studs b/c the 13" drums were thicker than the 11s. The e-brake cables were b/c I had an early 70s 11 inch set up and went to a later 80s 13" set up and at some point they...

    6 inch lifted 1973 truck back to stock/how to do it?

    I got stock rears for my 75 off Amazon. Rockauto lists them as well. Or you could try https://www.sdtrucksprings.com/. I got them off Amazon because I got free shipping. ground shipping on a couple springs can be as much as the springs themselves.

    Which A/C compressor did I have anyway?

    A6 , You're missing the top rear bracket. And the brackets from the compressor itself.

    1985 small block 350 won't start

    Pull a plug and see if it's wet. If it sits for half hour and wouldn't start but will start if you leave it for days, the carb could be leaking and fuel puddling and flooding the engine. You can try starting it will the throttle wide open and see if it'll start.

    Door mirror reinforcing plates?

    Kinda hard to see but the tab catches a screw from the inside to hold the plate in place and the screws from the outside just screw into it from what I remember. When it gets over -10 I might be able to find my old mirrors in the garage to show you the factory parts.

    Front frame bent?

    Thought that looked newer than 72. But still section 2 http://www.mediafire.com/download/wesxnrokz4n3x39/ST_330_81_1981_Chevrolet_Light_Duty_Truck_10_to_30_Service_Manual.pdf

    Front frame bent?

    From your name I'm guessing it's a 72. The frame measurements are in the service manual section 2. http://www.mediafire.com/file/nv3m0s4hz21guhc/ST_330_72_1972_Chevrolet_Truck_Chassis_Service_Manual_10_to_30.pdf/file

    Brake Booster or Master Cylinder ISSUE?

    If the rears are adjusted out properly and are not the problem, then I would bet on the master. Sometimes the bore in the master can have crap in it that doesn't affect anything ........untill you bleed the brakes. Then you move the piston past where is usually lives, get into the crap which...

    Some timing questions (experiencing some spark knock)

    That plate is affixed to the shaft. Look at c10mixmasters photo above. The welds are not wrong. The rest of the assembly floats around the plate to allow for the advance.
