This might be handy for you junkyard cruisers... a U-joint ruler I "acquired" this ruler from work: As you can see, it's got inches and all the important driveshaft U-joint sizes marked on it (including some that most of you will never use... like an 1880!). My thought was that y'all that were interested could print it out on some greeting card stock, laminate it, and go measuring away. But I forgot that the CK5 pic gallery only allows 640x480 max pic size. So if you would like the fullsize image... PM me with your email address and I'll send you the big picture (2820x432, 181K). You must send me an email address, or I can't send you the fullsize image.
