EASIEST 4 to 5 lug CONVERSION. Only need rotors from February 16, 2010, 12:13:29 AM I was at the junkyard today getting a new rear bumper cover for my 85 Tbird. I asked the old guy for prices on rear axles and front SN95 Mustangs. I told him I wanted to do a 4 to 5 lug conversion. OH! he says yeah that. Well s**t thats easy. Just use a Ranger or Aerostar front rotor with the old rotor's bearings. A something or other. He couldnt remember. But I did find this link from modded mustangs about it.http://www.moddedmustangs.com/forums/2-3-mustangs/50810-ranger-rotors-5-lug-swap-4cly-mustang.htmlI looked up on Napa prolink and the Aerostar/Ranger rotors are 10.28" in diameter and 4.14' tall, vs a standard Bird/Cougar's 10.08" and 4.01" height. (DOesnt include the Turbocoupe's 11's) Im going to the junkyard and going to do some swapping there to find out. Quote Selected
EASIEST 4 to 5 lug CONVERSION. Only need rotors from Reply #1 – February 16, 2010, 12:25:08 AM They won't work...bearings are all different.The ONLY way to get 5 lug fronts is: A. Lincoln Mark VII Rotors, or B. 94-96 Mustang rotor, caliper, spindle, and associated parts.You CAN use the ranger/aerostar rear axles, but, there's the issue with the rear drums...I'm going through this now.Best just to swap the disc brake rear from the same '94-95 Stang in, and also use a 93 Cobra master cylinder. I'll tell ya, piecing together a system like what I am doing is a right pain in the ass. Unless you have more patience than I do...But to reiterate, ranger/aerostar rotors will NOT work on a Tbird's spindle. At all. Quote Selected
EASIEST 4 to 5 lug CONVERSION. Only need rotors from Reply #2 – February 16, 2010, 12:40:49 AM Ranger / aerostar rotors work on Mustangs and my parts listings show mustangs and tbirds take the same rotor (pre 87 stang and non TC birds right up to 88) I know the inner bearing and race need to be changed, but beyond that why wont the Ranger rotors work on the tbird ?

Now I havent seen this, but like I said Ill be going to pullapart to try it, Lots of usuable parts and the tires are all off and jacked up! Quote Selected

EASIEST 4 to 5 lug CONVERSION. Only need rotors from Reply #8 – February 28, 2010, 05:55:04 PM I think this is how it all knocks out but correct me if I am wrong.Mustangs:79-86 cars all have 10" rotors and the smaller spindles87-93 4 cylinder cars all have 10" rotors and the smaller spindles87-93 V-8 cars all have 11" rotors and bigger spindlesThunderbirds:83-86 cars have 10" rotors and the smaller spindles87-88 non TC cars have 10" rotors and the smaller spindles87-88 TC cars have 11" rotors and the bigger spindlesIf you have the smaller brake setup then you would use the Ranger rotors up front and if you have the larger brake setup you would us the Mark VII rotors up front.Darren Quote Selected
