Rear disc conversion

[1966chevyc20]

I have a '66 C20 and currently the rear brakes are not working as the previous owner put a hole in the drum somehow and just unhooked them instead of fixing them. I was thinking of finding drums and rebuilding the drums but while looking I found this rear disc conversion kit ( https://lugnut4x4.com/product/62-72-...onversion-kit/ ). I'm really interested In this kit as it's affordable at $315 and looks like a good value. Has anyone used this kit and does anybody know if the stock 16" wheels clear the discs??? Thanks
