A Body Disc Brake Swap 101

Good thread .
I aquired a 1969 barracuda with BBP. setup with discs from a 1973 Dodge dart (I beleive ). It came with 15 inch rims and now has P215 R15 95H tires which touch the fenders in a turn . I beleive this is what caused the previous owner to crash the car and led to my aquisition of the car . The car would originally had 14 inch bias ply 70's . I either put narrower or lower profile tires, create an abnormal lift, customize or roll the fender back (unless something else is incorrect??). If there is a post that resolves this problem could someone direct me to it . I don't want to start a thread if the info is out there already and I beleive someone must have tried this before. Any advice much appreciated . Thanks
