How to tell if I have a 2 piece or 1 piece rear seal?

Hey,

Well I found a donor for a 6 speed swap for my car, it is an lt1 car and I want to make sure I don't need that expensive flywheel. From searches I have found that they changed styles around 86? My car is an 87 but I have no way of telling when the motor was made, its converted to carb. I can tell you it has a short water pump on it, and I put crane roller rockers on it. If either of that helps, I don't want to tear into in to find out lol.

86 and up are 1 piece rear main.

Look under the car at the back of the oil pan where the rear seal is. If you see a big shiny aluminum thing back there its a 1 piece rear main.
