I can't see how it is possible to have a good connecting rod after it has had a bearing spin inside of it.
I know that the Toyota bearings (OEM) are made up of different layers of metal, but the outside of the bearings is iron, if I am not mistaken.
Some aftermarket bearings are all aluminum.
Back to the OEM type, if those ever spun, I would bet my money that they did do some damage to the rod, and a good chance that the crank may need to be cut also.
