12 bolt 3ch into my 4ch stock car I'm getting a 12 bolt that has a 3ch setup and my car is factory 4ch. Is it possible I can hook it up and have ABS still work? Or will both ABS and TCS be non functional? If not, what would be required to make it a complete 4ch rear?

Well at first I could not find much with a search but Google has helped... Looks like I need axles with the reluctor rings on the end. Is it possible to "add" reluctor rings to the axles or would I need to buy new ones? I see people talking about pressing rings onto other 10 bolt axles, but what about pressing them onto a 3ch Moser 12 bolt axle?

Long story short I bought a 3 channel Moser for my NON ABS (non working lol) '94 Camaro 383, and once I was done with the car and willing to move on I kept the rear. The issue was the 2002 T/A was a 4 Channel and most certainly worked and I wanted to retain the ABS function.
Talked with Moser and all I needed to do was have the axels machined and fitted with a ABS exciter ring which I just took the axles out, pressed out the bearings and sent it to them. Between shipping and parts it was like 60$ and put the LS1 backing plates on and had the bearings re pressed and used the 10 bolt dust cover.
Worked perfect from there!
Also to mention since my ABS did not work my rear is not drilled for a 3 Channel so I would need to have to drill it to make it work. You would need a pipe thread or even use the stock Sensor to keep the hole blocked.

I would speak to them to get the specs OR have them mail you rings for those axles and then go local for the machining and let them know what your looking for. I am not a machinist and I do not know how much of a gap is needed between the axle flange and the exciter.

You will need to have your axles machined to accept the 4ch reluctor rings, and use your existing brake backing plates to mount the sensors. If down time is a problem you could go the route you mentioned, buy new already machined axles and sell your current ones after the swap.
