Small to large bolt pattern swap

I know everyone is asking about this and I have tried to read all of the responses,but I am still a bit unsure on what vehicle can be used for this small bolt(4") to big bolt(4.5") pattern swap besides any "A" body. Help , Help, Help. This will be done on a 1972 Duster 340 with a 4 piston caliper set up at the front [email protected][/EMAIL]
