2002 Mustang Bullitt Wheels on a 1969 Valiant

i to put my ralleye wheels on the old ladys 2001 mustang to try to moparize it a little, she made me take them back off. but yes the ralleyes are for my 76 valiant, so it seems like the bullit wheels should bolt on, but backspacing might be a question. i had some 15 inch cragars with 245 /65s( i believe) that were about at the limit for clearance.
