what rims are those exactly I have been looking for a set of tourq thrusts for my fifth ave but cant seem to find any that fit I am looking to get a set like this right here I just need to know if these will fit without modification to the car and if someone can send a link to them keep in mind my fifth ave is has a stock rear end but I might upgrade to the diplomat police rear end in the future as long as the rims and tires I get mock up

those are OEM Ford Mustang Bullit wheels from the late 90's through 03/04? they are +30mm offset. I used a set of 6061 billet bolt on adapters that were 3/4" thick (the lugnuts holding them to the car fit in a pocket in the wheel between the lug holes). so if you get a set of 17x8 wheels with a +10 to 12 mm offset, they will fit your M body perfect.

As an aside, if you're looking for lower gears for your M body, a jeep XJ cherokee rear end is basically the same width. you'll need to cut off the old perches and shock mounts and weld on new ones, but most in junkyards are chrysler 8.25" rears with 3.55 gearing (auto) or 3.08 gearing (manual)
