I finally decided to mod out my daily driver 95 gt. I am also in the process of selling one of my would be projects, 88 gt hatch. I have collected a $h!t load of parts for the 88. Basically, I spent last night trying to find out want could be used on my 95. I came a across a few. So my question is, what is the different between the msd pro billit for 87-93 and the 94-95? I was thinking it was the control mod.?
