    Do we have a show us your shop thread?

    Time for an update, I see - We moved last May, from the Detroit metro area to closer to Lansing. Part of a master plan to be closer to daughters/grandkid and also downsizing in preparation for retirement. It's a smaller home, with an upstairs garage for the daily, and then a lower "walkout"...

    Mystery hole on fenders

    Correct. Hole for body trim. The holes eventually went away because they were a spot where rust could originate. K

    Would be interested in thoughts about tonneau cover options for a 79 longbed.

    I have some thoughts: 1 - I wouldn't do a one piece. The 2015 I just bought had a one piece on it and the problems were two fold: a - if you had to haul something that wouldn't fit under the cover then you'd have to take it off. That could be a one person job, with some cleverness, but was...

    Richmond gear is this a 3.73

    3.73 should be 41 on the ring, 11 on the pinion (ie 11:41 or 41:11 as stamped in the gear). K

    Emissions question

    I have no recollection of how I found this. Just google, I think. K

    Emissions question

    I didn't suss it out line by line but I think we are saying the same thing. The only item I would take issue with is the picture of the G Van exhaust, which would not be correct for this discussion (it shows a cat). G Van sizes are staggered a little bit compared to square pickups, that is: a...

    Richmond gear is this a 3.73

    Count the number of teeth on the ring gear and divide by the number on the pinion. That's the ratio. K

    Emissions question

    According to the info packet the LT 235 is the base tire with C6P. K

    Emissions question

    You've reminded me of something: for LD emissions the TRUCK is what gets certified, so the emissions/tune up label goes on the rad support. For HD emissions the ENGINE is what gets certified, so the emissions/tune up label goes on the engine air cleaner. 84GMCSierra - you might check your air...

    Emissions question

    Totally off topic, but I see it came with load range D front tires and load range E rear tires, and no spare. Been a while since I've seen one with different tires front to rear. K

    Emissions question

    I was not able to find the detail I was looking for in the '84 generic info packet, but I found it in the '83 packet. I don't recall that there was any difference for '82 through '86 so it should be appropriate. I also checked the '85 information and it was the same as '83. See page 114 of...

    Emissions question

    Correct. That's an easy one since C6P = 8600 lbs GVW K

    Intro from an old Assembly Plant guy

    I had a new reproduction window sticker made for the red truck. This was done by [email protected]. We did everything we could to make it as accurate as possible, using the original invoice, original SPID, and other contemporaneous references. K

    Dexron II or Manual Transmission Oil??

    Yes. M20 is the RPO code for the SM465.

    Dexron II or Manual Transmission Oil??

    They are referring to the New Process A833, which is the three forward gears plus overdrive trans. It uses auto trans fluid. The M20 with the creeper gear uses gear oil. K

    Project is stalled. Cannot solve brake problem

    Joining late; skimmed the thread and didn't see where he admitted going from manual brakes to power brakes - but - by way of help: Manual brake pedal ratio (A/B) = 6.5:1 Power brake pedal ratio A/B (vacuum boost) = 4.5:1 Power brake pedal ratio A/B (hydroboost) = 5.6:1 K

    Axle ratio help

    Correct. For base axle GQ1 the SPID shows GQ1 but doesn't specify the numerical ratio, because it varies (as shown on the Powertrain Chart). For an optional ratio: The SPID will show the RPO and call it out by name (ie, GU6 = 3.42, GT4 = 3.73, GT5 = 4.10 or whatever). K

    Axle ratio help

    Well done, Lego. Just to flesh it out a bit more: I see C20903 W LT9 with the three speed auto (non overdrive = MX1) so I'd call it 4.10:1. K

    Coil Spring Insulators?

    Don't hold me to it but I don't recall it having them in either the top or the bottom. K

    1973 - 1987 Step Side fender splash aprons

    We used to call those "B96 Nails". If they hit torque but did not fully seat the assembly line repair man would whack 'em with a hammer (rather than get a screwdriver) to set them down flush. K

    1973 - 1987 Step Side fender splash aprons

    Nope. You are not missing anything. Zach - on the other hand - is missing this B96 molding screw right here. ;) I'd check that LR tire. K

    1973 - 1987 Step Side fender splash aprons

    I am sorry to hear that. Keep in mind we built 15 million squarebodies. If 10% were stepside beds then that's still 1.5 million trucks. If those trucks went 100,000 miles then that would be 150,000,000,000 miles without a fuel tank related incident, that I am aware of. You might consider...
