[Shotimes] rod bearings

[Paul Nimz]

I had a bad knock in my '93 with 150k on it.  I had some standard bearings
that were to go in a different motor.  Well I needed the car to be running
over the weekend so I decided to swap out the bearings.

One of the bearings was broke in half.  Two other cylinders had considerable
copper showing.  I just swapped in the new bearings and am quite happy I
did.  No problems in the last 10k miles.
