Differences Between the '85 & '86 IROC??

Just like the subject says... I am looking at getting an assembly manual and I can only find one for the '86. What are some of the differences? Would I be able to use the '86 manual?

For the most part, they are the same. Some of the electronics components will be different since 86 had the 3rd brake light and also the auto dimming rear view mirror, to name a couple. Also, there were engine changes in 86 that dropped the hp from 85's numbers. These changes alone could be enough to stay away from the wrong manual.
