Rear LS1 brakes and Front C5 on 67 Camaro

[Cruiser]

Ok, I have not decided on wheels yet but I want to upgrade my brakes.

At the momment I have stock 15 inch rally wheels and need to know if:

1: I use the LS1 rear disc brakes from the 98-02 Camaro on the rear will they clear my 15 inch rally? If not will they clear a 16 inch or 17 inch rally in steel.

2: The same question for the C5 fronts. I know they will not fit behind my 15 inch but will they fit behind a 16 or 17 inch steel rally wheel? I am thinking the "hybrid" set up here for better wheel clearance.

Goal here is hopefully I can go rear disc right now and use my 15 inch wheels, then upgrade to 16 or 17 inch wheels and bigger front brakes in the future. It's a budget thing.

BTW: I have front disc on it now from a 69 Chevelle, basicly stock GM brakes.

Thanks
