I am getting ready to do the same maintenance and will go with Mopar parts. Agree with Cozdude on the packs however might consider replacing the once covered by the intake while it is open.
Update.
Voltage was at 14.4 and this morning it dropped to 12.9. That “A” start stop light is back .
Any ideas. Alternator is going?
Also had to use air compressor today but did it while engine is running
