I would have to agree with Carl here.  The differential pin problem, while
it is the most common problem for the MTX, is not all that common.  The rod
bearings on the other hand, are becoming an epidemic.  Who knows, maybe it's
age.  I remember the first publicized case about 2.5 years ago about a kid
that just bought a 93' ATX with IIRC 110,000 on it and it spun a bearing two
weeks later.  I have cars documented as low as 85,000 miles spinning
bearings.  My bet would be that if you take down a 100,000 mile motor right
now the bearings would be showing copper.

Bruce Malachuk drove to the convention and home with a spun rod bearing.  I
beleive his car has less than 100,000 miles.  I would place my bets on rod
bearing failure over differential failure any day.
