    I think I know why my truck likes to "judder" every now and then. It's been really pissing me off, because I KNOW how to drive a stick.
    So hopefully it isn't too hard to replace these mounts.
    There is a local welder who can put a stick to the cross member. The mount on the passenger side is held in place by gravity.
    It should be so sweet when all this is fixed.
    I don't like our dependence on technology, but I love my iphone's ability to get photos of all of this! Cool stuff~

    By the way, anyone know where these motor mounts can be had? It could just be me, but it seems our host only shows '54 on up. (?)

    Thank you, Bill! The first one looks just like it. Of course, so do the rest of them!
    It's good to know they are out there and don't cost an arm and a leg.
    Guess I won't be driving my truck for a while however...

    Shudder? Looks more to me like the drivetrain is saying "I am thinking of leaving you Zig"

    It's like you don't know how to drive a damn stick shift! I can't wait to see how it drives with new rear motor mounts and the cross member welded back up.

    Might even inspire you to get the bed on the back Zig.

    Don't feel bad Zig. I once had a sleeve, around the pilot bearing on a Kenworth, I owned, come out and leave the pilot bearing with about a 3/16" gap all the way around it. That made the clutch grab so bad, it was literally "in", or "out". No matter how easy you let the clutch pedal out, it would grab, and the truck would just jump. Talk about looking like an amateur! Not to mention, the abuse on the whole driveline. And I couldn't figure it out, until I pulled the transmission, and clutch. I could hear a rattle in the clutch, but, couldn't see it.

    Sorry I didn't take pictures. I know how you require pictures. But, I assure you, it did happen.

    Steve.

    judder

    [juhd-er] Chiefly British

    verb (used without object)
    1. to vibrate violently:
    an old automobile with a clutch that judders.

    So is there some reason the motor mounts our sponsor sells won't work? Rear Motor Mounts-pr.-Classic Chevy Truck Parts

    It was the Chiefly British part of the definition that made me think it was shudder.

    Nah, if it was British it would make no matter what it was or where it was located it would leak oil. GM inline sixes had a terrible mounting system---essentially a 3 point mount since the front was two bolts nearly touching each other. My 37 Buick is a 235 with two extra cylinders with the same mounting so I welded extensions onto each side of the timing cover mount plate and then used flat head Ford mount cushions at the end of the extensions. Of course a couple months after giving it "the cure" my BW decided she would like to drive it on occasions so in went an automatic which would have cured the Judder without all the sweat, cuss words, cuts and burns. I've given her 48 years to shape up and if she doesn't shape up in the next 25 it's turning serious.

    HA!!! Good luck, Evan!
    During the Christmas break I will install new mounts and hope to be impressed. Next stop, welder to beef up the cross member.
    As far as our host and their motor mounts, I will have to take a closer look.
    What I like about what I found is it specifically said GMC, not just Chevy.
    Not sure there is a bit of difference, but~~~

    I've yet to take a close look at the front mounts, but Christmas break is right around the corner. I'll have to work in some quality time with my truck.

    BTW Bill, I actually set a bedside on a pair of saw horses and have installed a 3M wheel. I'm ready to slowly start stripping paint/rust.

    Hey, Mr. "we need pictures" Zig. It's pretty slow around here. We would look at a picture of the bedside on saw horses...
