Sterling Jacuzzi tub faucet leak repair

I have a three handle shower tub faucet that has leaked for years. I replaced the stems last year, but recently learned that the stems the hardware store gave me to use were the wrong ones. I brought in the original, and being a novice I was under the impression that the associates working there had the knowledge to give me the proper replacement parts. Against my better judgement I used the Price Pfister stem replacements that were given to me by the sales associate. It started to leak shortly after and washers have since been replaced twice.

There was a leak on the main water shut off, and since the water had to be shut off for the repair, I decided to go ahead and replace the washers, or rebuild, whatever it would take to stop the leak. Since there was issues with the diverter, I decided to go ahead and rebuild or replace that too. That was when I realized my gut feeling was correct, and the stems were not the correct ones. Before I went to the hardware store, I went online and cross referenced images and descriptions of older faucets and the diverter. I found out the original parts were/are Sterling.

Beings Sterling is no longer manufacturing these faucets, I had to find either an after market repair/replacement kit or find somewhere that still has the parts. I prefer OEM, and found a plumbing supply that carry Sterling parts. Since I no longer have the original stems, all I had to go on was the diverter and the original seats.

Knowing how important it is to have the seats in good shape, I chose to replace the old ones. I cleaned up the inside of the manifold as much as I was able. It didn't appear to be stripped or gouged in any way. I used a plumbers brush to clear any debris that may be left, and blew it out.

I purchased all 3 new seats, H/C stems with original washers, new diverter stem and washers, and all the trim.
