5 lug front rotor conversion...need help

I am in the process of swapping out my 4 lug front rotors for a set of 5 lug rotors. Im keeping the front brakes 10" -SAME AS STOCK. The rotors are from a 2WD 1984 Ford Ranger pickup, which is supposed to be a direct swap if you dont want to upgrade to a 11" brake rotor. Anyway, does anyone know if I should use the bearings that TIMKEN lists for a mid 80's Mustang? Or should I use the bearings that are listed for the Ranger pick up? The part number listed for the seal is the same for both the Mustang and Ranger(#6815).
The Ranger lists the inner bearing as(#SET6) and the outer bearing as(#SET2)
The Mustang lists the inner as(#SET17)and outer as(#SET12).
Does anyone have experience with this?

You might want to check this page out... http://www.coolcats.net/tech/advanced/4to5lug.html It appears that isn't a direct bolt on swap. It mentions what to do with the bearings as well. Good luck!

I DIDNT THINK IT WAS THAT COMPLICATED. I had read that it was just a straight forward swap. Actually the swap will be on a 80 T-Bird which uses the exact same 4 lug rotor as the 79-93 Mustangs. I had been under the impression that it was just a matter of proper bearing selection. The article you pointed out said that the Ranger rotors are also .25" larger than the 4 lug rotors, but the Ranger rotors I picked up, look just the same as the 4 lug set I currently have on my car. Hopefully we can get some more feedback about this, so that we all can find out. Thanks

If we have an 84 ranger rotor in stock I'll try to measure one at work tomorrow. Or, if you have one, you can just measure it and see if it is 10" or 10.25"...

I measured one of my Ranger rotors. It measures 10.25". The thing is... I'm almost sure that it matched up perfectly with the old scrap core rotors, that I got rid of when I picked up the Ranger rotors.I'll know for sure when I remove the 4 lug rotors that are on the car right now. I had been under the impression that a 10" rotor was actually a little larger than 10" across, since the machined area generally ends about 1/8" from the edge.

I have the 10.25" ranger rotors on my 79 coupe and they only required a little die grinding on the inside of the caliper to clear and it was not much work at all then matched up the correct bearing from the 2 of them and it all fit just fine. Good Luck

Here is a link to a few mustang things including 4 to 5 lug conversion on 87-93 mustangs.

Here I think this one covers about everything. Hope you find it helpful.

I did the swap with my 90 stang, I think I used the stang bearings.

Are you sure that your spindle has the correct O.D.?
