Anybody know what the difference between the distributor for a stick car or an automatic car is on an 85GT distributor? I am puting a carbed 5.0 in my 93 vert and need to see which one will work best. I think I need to use the 85 piece because the motor is a roller cam version out of my 89GT. I will either be using a C4 or a T5 trans, havnt decided yet.
