Wow, RacerX you are my model for calm in the face of adversity. Personally, I would
be flipping out if I just rebuilt and installed an engine only to find out about the
wrong bearing size. I have done many less frustrating things and gone mad for days
thinking about all the wasted and lost time. Better way to look at it...what a
learning experience. I love that! I aspire to be half as accepting of the problems
inevitably incountered when being a backyard mechanic.
