    85 vent windows

    1989 GM switched to the new 1-piece seals on the Blazer/Jimmy, Suburban, and crewcab trucks. Less wind noise

    Steering Wheel Too Close '84 C-10

    I installed a 1988-94 GM full size truck bench seat into my '83 C10 Silverado... I gained a ton of room. Lots of us install the steering wheels out of these same trucks to also gain some "wiggle" room. The horn contact wire has to be changed. That's all.

    A 1986 GMC Sierra Classic stepside (or Silverado) is very rare. Most were el cheepo base models. A factory tach too!!?? Amazing!!

    Glass lock strip replacement

    You can replace the chrome insert with the "Scottsdale" black insert too. This way, in 10 years, you do not have to worry about that new aftermarket chrome insert breaking down again.

    Transmission Fluid Question

    ..... I would have added a bottle of Lucas Transmission Conditioner if she was a quart low. Good stuff.

    700R4 Transmission Questions/Issues

    I'd drop the pan for inspection. Replace the filter, add the big bottle of Lucas Transmission Conditioner, and top it off with regular Mercon/Dextron IV. This will be a 50% fluid change. Then drive her a bit, let Lucas go to work....

    What year bed is this

    Top photo is 1985-87 style. There is a plastic shroud the fuel hose neck screws onto, via 3 small screws.

    Rear Splash Panel

    1973-80 I see them on trucks far more. I added a wrecking yard set to my '83. GM stopped using them after 1980. Cost cutting measure I am sure....

    What year bed is this

    You are 100% correct, and yes, the plastic filler neck "shroud" is missing here. So you need the 3-screw metal style, 1984-87 model, fuel filler to hose now too.

    8' bed question

    1977 will have a round, external gas cap. 1979-84 have the square fuel doors with the 2 bolt filler neck attachment. 1985-91 have the same square fuel door, but the plastic, 3 screw, filler neck inside
