    Sad Discovery: GM 10 Bolt Fails

    Isn't that a gov lock? Can you get internals for those? Is it worth it? I'd probably rebuild it with an open carrier if you're not going to wheel it. Or a mild posi. But I wouldn't put money into a gov lock.

    Rag joint question (see picture)

    Here's what the 74 manual has to say.

    Rag joint question (see picture)

    Yes. The missing splines go where the flat spot is. The pinchbolt passes at the groove that is around the input shaft. Remove pinch bolt completely and replace when the rag joint is on the shaft and the hole is lined up with the groove.

    Rag joint question (see picture)

    There should be a flat spot on the input shaft of the steering box. That's where flat spot goes.

    Fusible link?

    Chances are there was a pinched wire in or around the column and was shorting to ground thru the rag joint/steering box while the top of the column was loose.

    Brake Master Cylinder, what adapters do I need to make this work? Pic's inside.

    Fyi guys. 1/2 ton masters have front res to front brakes and rear res to rear brakes. 3/4 and one ton is opposite. Front res is rear brakes and rear res is front brakes. Make sure you plumb correctly.

    Rear end gear ratio change or transmission change ?

    Fyi. Sounds like either it's not shifting or it's not really spinning 5000. Unless you have serious low rear gears.

    Where's everyone mounting their CB's

    I used to have mine down under the dash and at one time on the front of the center console. Made it pretty easy to reach BUT If I was on the skinny peddle I couldn't hear it without maxing the volume. My K5 used to be super loud. Once I finished the cage and put in an overhead switch panel I...

    Fixing vapor lock now that I barely made it home, experience with 3 port filters?

    So. Just a crazy idea here. I've read back thru this topic and can't find any mention of how your tank is vented. Is the charcoal can intact? If not is the line open? or plugged? I've seen before when people pull all the emissions stuff off and plug every open line that the tank starts to...

    Front edge of hood sitting high.

    I'd say you have an early 70s hood with a late 70s remote release hood latch. The safety hook was oriented differently on the early "outside" release latch. Should be able to pop a slot in the hood and get it to work. There a good witness mark on the hood. Good news is it looks like you figured...

    This makes 0 sense to me! Heater hose route

    Hey man no worries. The 86 manual shows the path I describe as well. Plenty of variation thru the years, though so idk either...but if you think about the coolant flow on a std rotation water pump. Coolant goes from passenger tank (cold) to water pump (cold) to engine, thru engine to intake...

    This makes 0 sense to me! Heater hose route

    It IS an either or. On non auto vehicles it went manifold (hot side) to core, core to water pump (cold side) On auto vehicles it goes manifold to core, core to radiator, it does this to dump a little heat into the cold tank of the radiator where the trans cooler is to get the trans up to temp...

    steering box bolts

    The spacer provides for proper stretch on the fastener to maintain clamping force. I've seen many people omit the spacer and deal with repeated loosening of the box.

    Blower fan/relay

    This is the 90 diagram. Purple goes to the blower. If it's not hooked to anything that is your problem.

    87 blower motor

    As far as I know there is only one wire that goes to the blower itself. If power is applied directly to the terminal on the blower motor itself it should run on high.

    Fixing Rear Leaf Springs

    You might be able to get the ones you want from Amazon with free shipping if you're prime. Before I left CA last year I ordered all new springs for my blazer and got free shipping. Here's an example. A little more expensive but shipping is usually as much as the product now a days. Dorman...

    Double cardan ball

    Once upon a time I had a shaft built for me with a gm 3r double cardan joint in it. Many years later I went to rebuild it and found that the ball on that one was not replaceable, and was in fact a part of the yoke. Bummer. Went down to the junkyard and found a 70s Cadillac with the right joint...

    Rochester Carb tune ; Which is best method?

    I've never had issues with the lean drop method. I have two small screwdrivers tucked away in the toolbox just for the mixture screws Lean drop is what the factory manuals specify.

    Well, Here We Go!!

    Looks like a good starting point. Welcome to the "club". I really dig that siphon bulb in the fuel line. These trucks are pretty simple. Should be relatively easy to un-******* the jerry-rigging.

    New guy with a ton of general questions...

    First, figure out all the things you might want to add to the truck electrical wise to figure out how many circuits you'll need, then double it. I started out many years ago adding a pair of lights, then another pair of lights, then a cb (shows my age) then a backup lamp, then.......... Then I...
