    Harmonic Balancer Woodruff Key - 4.2 Crank

    So this seems incredibly stupid but maybe I'm not the only one to find this out.

    I'm building a 4.6 stroker using an early 4.2 crank in my '98 4.0 block. The crank was machined several years back for another project and sat on a shelf until I started this build about a year ago. Somewhere along the way the harmonic balancer woodruff key was lost, but I didn't worry about it because I had the one in my 4.0 crank. It's the last thing I need before I finish the front of the engine....and guess what? The key in my 4.0 crank is too small, the width and length are right but the depth is too shallow (when installed it is at the same level as the crank surface which would allow the balancer to spin on the shaft). I can't seem to find this key anywhere locally...anyone had this problem and found the right one???
