I didn’t think 13’s would fit on anything but early 90’s Town Car’s. I know 13’s won’t fit my 95 TC with the bigger front caliper, 15’s didn’t even fit with shaving my calipers and 98 and up TC’s went to bigger brake setup / wheels if I recall. Got to swap spindle / brake setup from older cars with the smaller setup. I don't think the 13x7 will fit without some work.
I'm sure its been figured out after a month, but just browsing the forum.
