That's a good plan. I have the instructions for replacing the regulator (and brushes) and its a little involved.
Some are switching to the Delco Remey 28SI alternator (its brushless) but unless you can get it cheaper (or faster) I don't know if it will make any difference.

Another check.  Engine off voltage across chassis batteries is 12.2 volts.  Engine running 11.9 volts.  Alternator or regulator?  The regulator has TRANSPO 9000 HD on it.  The alternator says model 7613N along with a couple other numbers.

That 7613N is a good number.

Jerry, I forgot to mention. be sure the alternator you order (if ordering on line) has the correct mounting style.

On my coach the alternator uses a "pad mount" (mounts solid to engine), some engines have a "hinge" mount (a long bolt goes through the bottom that alternator can rotate on with a mounting ear at the top that you use to tension the belt). I don't know what style you have (I think it is pad mount) but in the photo I used from amazon that looks like a hinge mount - however it may just be a generic photo they used.

EDIT: Based on the photo you provided, you have a hinge mount style.
Good luck.
