Heartbeat City OEM Style Brake Kit with 2-piece Rotor

[Greybeard]

Although it's not a Camaro, I'm hoping someone can help me out.  My 1970 six cylinder Nova has "wooden" OEM manual drum brakes and the stopping power leaves a little bit to be desired ...L-O-L...(all parts are fresh and all work properly and it's stock-stock-stock). I've been thinking of swapping for an OEM style front J52 (Manual) disc brake kit from Heartbeat City. This is the comprehensive two piece rotor -- made in USA -- setup supposedly with a lot of correct parts - Heartbeat City Part Number BRK-1001A.

The question is, has anyone used or worked with this kit? What's the quality and fit like? Does it work well?

I other options available to me, but I'd really like to know about this kit. If anyone can help me with this specific kit (only), please let me know.

Thanks!
