    Speedometer Driven Gear

    Aw hell... I wasn't paying attention to the fact you have a 4x4. For the 4x4s the speedo gears are in the transfer case itself. The transmission should've had a blank plug installed instead of the rtv'd gear housing. I'd look on the tail housing of the transfer case for a similar gear...

    On door weather stripping

    I think mine just have some sort of adhesive holding them on, but I can verify when I get home.

    Speedometer Driven Gear

    I went to compare your pictures to the ones I took while doing my speedo fix and from what I can tell, you're missing the drive gear. That small one is for the governor. Here's the post where I have the pictures from mine. http://www.gmsquarebody.com/forum/showpost.php?p=212800&postcount=34

    Speedo is off but the formula says it should be spot on. I'm at a loss

    I like using this site... you can play around with the drive gear numbers to figure out the different combinations that will work for your set up. :) http://www.tciauto.com/tc/speedometer-gear-calculator/ :cheers:

    Speedometer Driven Gear

    You're correct that that gear housing is for gears with tooth counts from 36-39. There's another one for 40+. You really need to determine the gear ratio in the rear end before you can figure out which driven gear you need. There are a few different ways to calculate it. Here's a...

    Need speedometer gear drive

    Can you get pictures? I've always had luck finding speedo gears on ebay. There are also sites like http://transmissioncenter.net/ that offer all sorts of part including those gears.

    BBC valve guide help

    Those have some heavy duty inserts on them... I would think that you might be alright, but you can replace the whole guide if it makes you feel better. I had to replace one of the guides on mine when I busted it while installing a liner in it.

    Hydroboost Brake Pedal

    It's for a vacuum booster... Sets the actuator rod on the booster at bit of an angle and the pin on the pedal is smaller than the one on the hydro pedal. It's works in its current config, but I foresee it not being healthy on the booster in the long run.

    How to solve an exhuast backfire?

    My truck from high school started backfiring when the exhaust doughnuts failed at the manifold to exhaust piping. The exhaust leak wasn't real noticeable, but the backfire was. :) Just make sure if you replace those, you tighten the bolts back up evenly. I didn't/couldn't and the new...

    Rear sliding window help!

    These guys seem to have been able to cobble together parts from various sources to rebuild theirs. I'm guessing the parts would be similar for ours. http://67-72chevytrucks.com/vboard/showthread.php?t=559651

    How much MPG does your 454 get, and TBI conversion?

    I just figured out what my last fill-up came to on the mileage and I squeaked out about 11mpg in the Ol' Girl with mixed driving. She's carb'ed with a nearly tuned Quad and has 31" tires and 3.08 gears. So, I think I could probably squeeze a few more out of her if I tried changing a few other...

    Gearing with rpm rang

    Which transmission do you have? If you have either the TH-350 or TH-400, then 3.73s would put your RPMs around 2800RPM @70mph. 35's would bring the RPMs down to about 2500... The problem with taller tires is that it would hurt your acceleration. But, the reverse is also true in that if you...

    What have you done to your square lately??

    Got the ol' girl out for a little drive this morning when I took the dog to the vet... She's a happier truck when I get her out more often, but I still need to do a bit of tuning. The dog was pretty happy too... She loves rides in the truck. :)

    Quadrajet help!

    I found one so far, but let me make sure it's not the one I need... I know I have another carb buried in the garage somewhere, just keep forgetting to look.

    Quadrajet help!

    Let me look at my stash and see if I can find that linkage.

    Quadrajet help!

    Can you take a picture of that side of the carb? I have various linkages and the link that 350runner posted is a good resource.

    What have you done to your square lately??

    Took her out for a couple of trips out on the freeway to blow the cobwebs out and run errands. Got a compliment as I was about to leave Home Depot. Amazing how many people love these old squares...

    at my wits end on power steering pump

    Napa has gone the same route as the other parts stores lately... Had to get a remanned window motor for the car and it was the same brand as OReilly and Autozone, just rebranded as a Napa part. :doublepuke: Really a shame as I used to trust them to have better parts on the whole.

    Bumper Guard

    Looks like it was made for the later style bumpers. Would probably work with the early style with a little modification.
