    Carb help? (With pictures)

    Looks like a bunch of the linkages on the pass side are not hooked up or missing. Might be holding things in the wrong spots and/or jamming up other parts.

    Bilsteins 5100 on 75 k10. Rear shock mounting fit issues

    As I recall, which is getting harder as the years go by, the frame holes for the rear shock studs are 5/8". So ya a 16MM would be the right size.

    Rear body mounts for a 74 k20

    I've always done one side at a time. All left. Then all right. That way you're tilting the body side to side and not putting too much stress between cab and fender as that's exactly where the fenders rip on Blazers and burbs when you wheel them hard.

    73-75 k5 hard top seal

    In the Reference Library forum there is a sticky post with all the service manuals. Pretty sure the 73 is there. I know the 74 (where that pic is from) and the 75 supplement are. I actually have the 74 and 75 manuals but the PDFs are super convenient print what you need and if you get them...

    73-75 k5 hard top seal

    The bulb seal fits over the pinch weld the front header seal I believe glues on and has a screw in each end as shown. I haven't had my top off in over a decade so I'm foggy in the memory department.

    Time for new shocks. Look at these!

    I like the KYBs that I put on my Silverado. And you might want to put a put a brake drum back on there. :p

    Tires Plus says my Dually tires are too heavy to balance.

    one other possibility is that they cant fit enough weights where it would need to be on the rim to balance them, but then you just break the bead rotate the tire and try again. Sounds like somebody is tooo lazy.

    Wrong brake calipers?

    Also check the brake line hole. Early calipers 73-77ish should be a 7/16" banjo bolt. After 78ish should be 10mm.

    A/C Condenser Mounting Insulator

    They should just be well nuts. Available in the weird hardware and assorted dodad drawers of any decent hardware store. ACE or True Value. Not so much the big boxes Edit: I looked and stand corrected. Home Depot carries them.

    Help with the name of this part and what does it control.

    I believe that is the EFE valve. Basically a vacuum actuated exhaust valve that's part of the emissions system. See below.

    Quadrajet Choke missing?

    Yes. Your choke is missing. This might get you started but it will need a rod and works better with the little cover. Might have to hit up a restoration place or a junkyard.

    700r4 overdrive?

    Not an expert on the 700r4. But I do know that the TV cable is vital to the survival of that transmission. If you replaced the Carburator and didn't get that TV cable just right that may be part of the issue. I'm sure someone with more knowledge will chime in soon.

    Have i decoded this VIN correctly????

    That's exactly right.

    Have i decoded this VIN correctly????

    Nope. Those are K30 axles. Well, to be more accurate the front is a K30 axle. The rear could be a K20 14 bolt or a K30 14 bolt. If you measure spring pad to spring pad on the rear you'll know whether it's a K10/20 frame or a K30 frame. One tons had the springs closer together. K10/K20 rear...

    Have i decoded this VIN correctly????

    Not sure about where all the parts came from but that appears to be a factory 4-wheel drive frame. It also appears that you have a Dana 60 one ton front end and a 14-bolt one ton rear end. Great combo of parts. But I think its safe to say you have a Frankentruck. I hope you can get it all...
