T Bird alum front runners on 86 GT - Need wheel spacers?

Going to the track tomorrow morn [I should be in bed] and my buddy has an 86 GT. He has some Aluminum T Bird spares for front runners, and is planning on using them. The guy he got them from mentioned needing spacers... but the guys car is a 91 LX. I know Ford changed the front brakes to larger but forget what year...

On the 86 GT [still has the smaller brakes I think] does he still need spacers to run these things.. cause I did have two spacers here but cant find em for the life of me :rolleyes: & its getting late..

Info MUCH appreciated!!!!!!!!!!!! :hail2:
