Hi - Width wise I was looking at 7 inch wide wheels (13" x 7") with a suitable width tyre of a profile to keep the rolling radius of the wheel as close as possible to the original.
I know the width will be OK, I just need to understand what offsett I will need so as to avoid hitting the front struts and rear spring mounts.
As I mentioned,I don't mind the wheels projecting beyond the body line as I quite like the option to use fender flares and spacers to get the right look.
