    It's much easier to promise someone a "free" ride on the wagon than to urge them to pull it.

    Luck occurs when preparation and opportunity converge.

    Yep, call the shop that will be doing it and ask their method of measuring, it varies from shop to shop. Another point: Measure with the weight on the car resting on the tires at ride height. I did one where I had the car up on jackstands with the tires hanging free, and when I put the shaft in and lowered the car it was too long! The shop took pity on me and only charged me $ 25 to recut it.

    I only made that mistake ONCE.
