    Need H6 AC compressor brackets for 454

    @Squarebody1985 here's those pictures. FYI my truck is an early production '85 (11/84) with a single smog pump set up. Trucks produced after 1/1/85 had dual smog pumps, factory stainless headers and a different A/C compressor set up. I'm not sure it those power steer mounts were different.

    Rear Bumper difference?

    I’m pretty sure the van bumpers are wider than the truck bumpers. Track width is 3-4” wider.

    83 K10. 6" lift. Question

    I can't tell too much in the front, but it seems your front spring are short for some reason. The shackles look pulled forward instead of being close to vertical. Could just be optics. You could always get a shorter block in the rear with a taper to lower it and in the front take out a leaf...

    What size tires for 4 inch lift?

    Here's a few of my past trucks and the last is my current K30. FYI the K30 is only a 3" lift, but would be a 5" on a K20. Last 2 trucks (K15 & K30) I've run Tuff Country EZ Ride springs with ORD's Sway bar disconnect. 1979 K-15 3/4 ton axle swap 4" lift with 33 x 12.50 x 16.5s (same as a...

    Center dash speaker options?

    Here's the bracket my '85 had a the front dash corners. If you don't have them you may need to fab something. I put my speaker on the under side of the bracket to clear the tweater (yes those screws got trimmed).

    Rear Bumper difference?

    This is the correct bumper for a step side of that era. A fleet side would look too squared off I believe and the sides extend closer to the fenders.

    Does a lift kit exist for 2wd 79 c10?

    I know on our '89 Caprice police packages used the larger 1/2 ton brakes (12" rotors). I believe regular Caprices used 11". You may looks at some of the lift spindles for "B" GM cars. https://liftabrand.com/Product/4-12 These are 4.5"

    Drive shaft rubbing "Y" pipe

    On my '87 K20 I had years ago, I had a U shaped pipe installed under the drive shaft. This is to give you an idea.

    Advice please

    I'm a 4WD guy, so personally I'd go with the K5. A rust free K5 is a great starting point for someone. The nice thing is the patina is great on that truck, I would just due the mechanicals on it and clean up the interior. If a 4WD is just not your thing, sell it and use the funds to build the...

    Door panel recommendation

    I bought Coverlay through Rockauto. They were the cheapest I found. The panels are the same style as OEM, but have the 89-91 style cloth inserts. In the second picture you can see the factory style 81-88 insert. I'm going to add the non-pull strap trim like I did on my '79 (photo #3). The...

    2wd to 4wd conversion

    The 2WD also does not have the extra bracing below the frame for the brackets like the 4WD does.

    Show me your 8 lug wheels!

    Outlaw II's are the best wheel ever! Can you tell I like them? I should have used them for my K30, I just wasn't sure the 16" version would look the same as all my 16.5's did.

    2wd to 4wd conversion

    K30 and K20 spring hanger are totally different. K30 are almost vertical. The K30 is mine. The shocks mount inside the frame due to the location of the spring. Shocks are also reversed from a K10/20. Second group of pictures is a C20, but the same idea as a K20. K20 is 2" longer and has...

    Blows Hot Air When Off?

    There are some adjustments to the top of the heater box that close off the air flow from the heater core. I had this issue when I finally got the A/C hooked back up in my truck. I grabbed this off the internet. I believe in my case I needed to adjust the solid rod, just left of the circle.

    Rear Brake Line Bracket

    I have the brake line bracket. PM your address and I'll get it out to you. I thought I'd throw this out there since you have an '85. Unless you are building new lines or using a prior year design that doesn't have the weight sensing proportioning valve, here how I did my '85 K30 without the...

    Need help with installing a 454 in a 1979 GMC Sierra 4x4 frame

    All I can offer here is the pictures I took of my truck when the engine was out. K30 with a factory 454. Hope this helps.

    Stock 350 getting hot, but only on the highway with AC on

    Do you have a 16 LBS radiator cap? Just ran into this with a friend that put A/C on his '62 Belair. No over heating issues until the A/C was installed/used. Previously he had a 13 LBS cap which was standard for a non-A/C car. With the new cap, no overheating.

    Powered sub location?

    Sway bar bushings

    On my sway bar, I've burned them out before. Didn't have to on my current truck. I see you're lifted. I used these on my last two trucks. They're from ORD for $115. Gets rid of the bind the sway bar causes...

    Draw-Tite 41938 Hitch

    I don't believe Suburban or Blazer factory hitches work on trucks due to the difference in the rear frame horn shape.

    Draw-Tite 41938 Hitch

    I’ve seen hitches like the one you diagramed. Most of those are for F-450/550 or the old Chevy C3500HD (1991-02). There’s probably no issues with having the shorter hitch, it was just a problem in my Suburban 2500 group. 2000-06 Suburbans can bend the frame right behind the spring hangers...
