    Hvac blend door question...

    It's been a few years since I had all that stuff disassembled. The pod that points toward the gas pedal should be the one that controls the floor/defrost flap. It's the one at the bottom of the yellow box. The pod in the red box pushes and pulls on the blend door (second red box). That...

    15x10 Steelies

    In case you didn't know, the hub caps/wheels you displayed are 3/4 ton which have a larger diameter. The wheel shown is a 16.5". 1/2 tons have a 5 spoke cap like the picture below.

    What have you done to your square lately??

    If it matters, my K30 was made at the Janesville, WI plant. I'll trade to my trim and clips for a 2" cowl hood. :lol:

    FOUND - OE Hand Throttle - FOUND

    I have no clue. I'm just one of those guys that has one of those pipe dreams of putting a C50/60 cab on a new chassis and cruise it. Not sure if you are on Facebook, but there's a really good group on there (similar to this one) for C40-60 trucks. I'm sure someone there could help. I lot of...

    6.5" speaker mounting options

    If you have power windows and chose to mount them in the doors they need to be at the very front corner of the door or the window assembly will hit the magnet when its lowered.

    FOUND - OE Hand Throttle - FOUND

    C50-C60 trucks have those. Here's a link to a place that parts them out. https://www.vanderhaags.com/detailview.php?part=25102692

    Wheel offset

    My K30 had them when I bought it. Tight fit with a Dana 60, but they do fit. Tires were 265/75R16.

    Tachometer replacement thoughts

    I used an Autometer #2891 (2 5/8"). I screwed it to the shifter column. When I'm in drive it's straight up.

    For those wondering what the C60 dash looks like, here's a picture. This one said 1976.

    New in PNW

    Doubtful, too many things are different. I changed the front clip on my 80 back in the day.

    Adding a Suburban Gas tank

    @Frankenchevy fabbed up a dual tank set up on his truck. Maybe he can chime in or look at his build thread under the K30 section of Under Construction. https://www.gmsquarebody.com/threads/rebuilding-my-truck.20949/

    OER compared to LMC

    Let me know when you get these in stock. The LMC ones suck!! The adhesive only works for a short time and comes off.

    Hvac blend door question...

    Hopefully you got this fixed. When I had my box out I repaired the factory floor/Defrost flapper. Photo #1 From the factory there is a foam seal that deteriorates over time. I bought some Scotch felt furniture pads and cut them to fit. I reused the staples the arrow points to. It created a...

    Retrofit AC upgrade results

    I used a Sanden with my OEM set up. Works perfect.

    Front clip swap?

    Yes the wiper towers need to be changed too. The 73-80 are shorter to fit under the hood. You should be able to keep your wiper arms and washer squirters. I back dated my '79 to look like a '73-74. I like the earlier hood with the peak in the center and the amber parking lights.

    Dash speaker fit issue

    Rear Sway Bracketry Mod

    I would be afraid there would not be enough side movement to your new set up. I'm thinking entering a driveway or ditch at an angle and having the axle crossed up a bit. Just my 2 cents.

    How to measure 14 bolt drum?

    The 11" drum on a 14 bolt looks similar to the first photo. Photo 2 is the 13x 3.5" on my K30. On a 16" wheel, the 13" drum will look like photo 3. Fit is fairly tight. You would have a really noticeable gap with the 11" drum.

    Smooth ride

    This was my last truck and probably the best riding Square Body of the 8 I've had. I've had Rancho and Skyjacker kits on previous trucks. 4' Tuff Country EZ Ride front springs and a 4" block in the rear. OEM 5/1 rear springs. Shocks were Tuff Country SX8000. I think the best thing to add is...

    New "Old" Daily - 8.1L

    Yes the 8.1L loves oil. It's a design issue. There's no PCV valve, just an orifice under the intake manifold that causes the oil consumption. About 2 quarts per 3k miles. There is a fix, but I not worth taking it apart.

    Shackle flip

    ORD carries the 4WD rear axle front spring hanger. It is 2" longer than the C30 version. You will need this to make the flip kit work correctly. You can see the OEM hangers on my K30 put the spring eye below the frame (photo #2 & 3). Link...
