    Center hump

    From looking closer to the picture of the 87 4wd /auto there looks to be an indentation where a 4spd shifter would sit so I would agree that they are the same. Parted out a 85 2wd/4spd a few months ago but deleted all the pictures after I sold the cab.

    Center hump

    Thanks for the replies and the pictures. Clears up a lot of questions. Only question I have is there any difference between the 84-87 high hump with a manual 2wd and auto 4wd except the obvious hole placement for the shifters?

    Center hump

    I realize that. Got a high hump removable pan and it doesn’t fit the floor contour on my 84. Question is are the later floor pans different With the non removable hump?

    Center hump

    1984 c30 dually. Swapping to a nv4500 from a auto. Got a removable hump from a earlier truck and it is not even close to matching the floor pan. Correct me if I’m wrong but even the high hump floors from that year(84) was not removable? Is there that much difference in the floor pans? Local yard...

    Engine swap for street and towing

    For me the 8.1l 496 is a better option. Bolts right in and you can use your drive train as is. Use 454 exhaust manifold. Upgrade to a 4l80E and cruise at 70 no problem. Kodiac or van front drive would be nice but not totally needed. There is aftermarket brackets available. 6.0 ls engine would...

    Front hub extensions.

    Have realized that the 30 series rotors are thicker than 20. Will be using 30 series rotors if it will work. Looks like a trip to the upullit yard.

    Doug Nash OD

    Good info, most seem to not be aware of them or confuse them with the vette transmission(have one of them too). Rated gvw of 35,000;lbs it is far better than gearvenders. Most have decent luck with the gv unit but for pulling a load I wouldn’t have one. Currently have a Nash unit bolted to the...

    8.1 vortec into 1979 k30

    Did this swap in 2013 in my C30. look up 8.1 on here and it will come up. Swap is easier than a ls based swap. Just pullout your 350, swap over your flywheel/clutch/engine mounts and bolt it in. If you want air the frame will need notched or swap the van/medium duty truck stuff. One thing to...

Have two non tilt square body columns and two tilt columns from a 90 and 93 gmt 400 trucks. The Newer columns are 2 in longer from the upper mount to the wheel. Not good unless your...

    Clutch switch pigtail

    Thanks for all the replies and pictures. Things starting to show some clarity and some confusion. Think the pedals came out of a 87(been a few months). interesting that the same plug is for the wiper switch. Local pick and pull has several squarebody's and the plug should be a easy find.

    Clutch switch pigtail

    if you can get the switches out without breaking of the curly part off i will take them. most likely end up with new ones but nice to have a couple spares. how much money?
