Old change the belts to dayco top cog as in earlier post. My hemi would throw and break belts at rpms until I switched. No problems in 8 years. I was able to get a deal on a bunch of different sized unused belts from a nascar team to see what length fit best. I ended up with the 15470 for alternator and 15440 for power steering.

The first 2 numbers mean it’s 15mm or 7/16 wide the last 3 are length. The last number can be a 5 for half inch. So if yours fix good just measure them in inches and add that number to the 15.

I will bet your problem will be over with the new belts.
