CPP P/S kit problem and a brake question

[Nix62]

I purchased the power steering kit for my 62 but I'm having a hard time figuring out the mount plate and the backing plate. Only one of the holes lines up between the two plates no matter how I orient them.
I think that I may have gotten an non-matching pair or am I mad ?








And a follow up question............I have power drum brakes, factory with the hydraulic clutch/brake master cylinder. I'd like to put discs on the front. Can I keep the stock power booster and master cylinder and just substitute the disc calipers for the drum wheel cylinders ?

Thanks.
