How it works.
The DEADNUTS squaring tool is designed so one person can quickly square the rear end perfectly every time.
Simply slide the V-Block end of the tool over the axle and tighten the knurled clamping knob. As you are securing the tool to the axle you have the choice of using the built in level to measure at axle height at the motor plate or to set the tool so it measures from centerline of axle to center line of the crankshaft. The choice is yours, do what you believe is best but we put a level on there for some of you. At this point your tool is secure to the axle perfectly square and level or to the crank centerline and both of your hands are free. Now you move up to the motor plate end. Typically you would have to have a straight edge clamped to the motor plate because you have two free hands to run the tape measure. This tool avows you to simply hold a straight edge against the motor plate with one hand and with other hard unscrew the micrometer end till it touches the straight edge. Once the micrometer anvil lightly touches the straight edge, It is marked telling you how many turns too long, or too short on the rear heim you are. No guessing. No more wasting time. This is allot more accurate than a tape measure or yard stick type device. If you are 1/2 turn too short on the left side and 1/2 turn to long on the right, that throws the rear out of center by about 2 full turns on your Jacobs ladder hiem. Thats a huge difference. The car will roll much easier and the ball will be more free, every time. Not only is a tape measure not accurate or repeatable but it reads in 1/8th and 1/16ths, wich does not coincide with the turns on a 5/8-18 heim end. Each tool is calibrated to +or- .005", much more accurate and repeatable than anything else on the market. The object of using one tool rather than a pair is to ensure you're setting both side from the same standard and to save you money. The standard Sprint model comes with interchangeable anvils letting you square cars 37" to 40". The midget model will do 32" to 35" cars. Custom sizes are available.

HANG ON UNCLE JESSE!
After this hard crash we used the deadnuts tool to determine there was nothing bent int he rear of the car. AFter head on contact, my car jump over the other car, yes like Bo duke. It landed hard on all 4 wheels and was still rolling. the front of the car was bent up pretty well but the squaring tool showed the rear was still perfect. At the race track if you were to hop a wheel, bump the wall with your right rear, hit a big hole ect ect you can simply throw the tool on it real fast and know for sure if you have a problem or not. You can even do it with the car on the ground. Have one guy push down on the rear bumper so you can slip your ride hight blocks under the axle, let the car back up, unhook your ladder and put the tool on. right then and there you will know if you have issues or to worry about something else.
