    Reverse light switch and wiring

    Years ago, the previous owner removed the 3 on tree shifter from my 250/6 with Saginaw 3 speed, and replaced it with a hurst indy truck shifter. So, I have no backup lights. Where are the wires for the reverse light switch. I don't see any hanging wires by the tranny. I just want to install a...

    Brake switch removal

    You may be looking at the ignition switch on top of the column, near the firewall. The brake switch is pressed by the brake pedal arm and is easily removable just by standing on your head like this: I thought this photo (From Hammers Garage on you tube) was hysterical. How many of us have done...

    Speedo cable length for 81 c10 6 cylinder saginaw

    The factory shop manual says you gotta reach up from behind to change bulbs in dash.. I can reach this lower left turn signal indicator, but cannot get it out. Others, I have no idea how to reach them..

    What have you done to your square lately??

    I finally got a rubber pad on the parking brake pedal. Everybody wanted $5.99 for it, but only O'reillys had free shipping to the store. LMC wanted $24 for shipping it. Install was super easy.

    Speedo cable length for 81 c10 6 cylinder saginaw

    Speedo still working great. then driving to Boulder noticed the tach went out. Found the power wire had come out of the fuse box. On that ride I lost my left turn signal (Just the indicator on dash, outside lights work fine). Do I get at the bulb from the back of the dash, or do I have to remove...

    Speedo cable length for 81 c10 6 cylinder saginaw

    I fixed it. New cable.. The exact one I pulled out by part number on the cable, but new is 1 " longer and speedo is now working smoothly, for first time since I bought the truck. 3rd or 4th cable. All have been ATP-pioneer brand. New cable fit properly all around. This was the only problem in my...

    What have you done to your square lately??

    Finally! A cup holder that doesn't take up space on my seat. From Oreilly, magnetic and a good magnet. Says it holds 8 lbs. Derek Beiry at VGG bought these for his mustang for a cross country trip. Works great. Part # PTT0051

    Most affordable shipping for body panels?

    It's 621 miles from here to Kansas City, and the same back. 1240 miles/14 mpg = 88 gallons, at $3/gal=$270 to drive there and back. AMD wants $800 for one way. It would be a nice road trip if it wasn't kansas and sunflower season

    31x10.5 with 3:73 gears.700R4 trans. What RPM will I have at 70MPH?

    Your rear end should be (2000/2734) * 3.73 = you need a 2.72:1 rear end for 70 mph at 2000 rpm. Look at tire circumference to refine this calculation.

    31x10.5 with 3:73 gears.700R4 trans. What RPM will I have at 70MPH?

    Oh, you want RPM at 70- (70/51.2 mph)*2000= 2734 RPM at 70 mph

    31x10.5 with 3:73 gears.700R4 trans. What RPM will I have at 70MPH?

    Its simple. For each 1 engine rotation, the driveshaft will turn 1/0.696=1.43 times The rear end lowers the rotation from 1.43 to .383 wheel rotations (1.43/3.73). So, multiply your 0.383 by the circumference of the tire 97.4" for a 31 (approximately, but go and measure your own with a tape...
