They work great in new system. I chose to use all three caps and its working well.

Call I could post some more pictures if somebody thinks they can help me identify the rectifier, I just thought for the low dollar amount that they have on the Centroid rectifier I would buy it

The rectifier is the little black box hanging off the orange and grey wires in your first picture. The red disk is the inrush limiter. The tan square stick on top of the capacitor is a bleed down resistor to prevent the capacitor from staying charged when the system is off.

Now I notice what it says, “requires a 12,000+ MFD or higher capacitor” and I wonder if the two components won’t work together?

The center to center post is unique to the Capacitor that Centroid uses. Likely will not fit your capacitor (ask me how I know this)
Its not a terribly expensive assembly, and they fit nicely under the All in One DC

Not unique, but not universal either.

Craig did already say his capacitor measures 1.125" between the terminals, so the CAPBRDLO should fit.

I don’t think the red disk is the in rush, I believe it’s the snubber as it’s on the coil of the contactor

Yeah, the red part is probably a snubber. The OP does refer to capacitors and snubbers. I dont see any inrush protection in the first picture. Although the AC wiring has been removed from the rectifier. It would have been in series with that wiring. Pretty important it has inrush protection or that rectifier is going to go POP! Well depending on the ESR or the capacitor, the impedance of the source and wiring and the peak current rating of the rectifier.

The rectifier is in his first picture as is the bleed off capacitor. The inrush device is not present as pointed out. Centroid uses a MS32 2R025 Inrush current Limiter:
