I ran my Chasis number through CAPS and there are two parts listings, but I couldn't tell which was which.

I spoke to John at Rocky Mountian Imports. He's sold a couple clutches to people and it is his experience that the Shorties typically have the dual mass. He ran my code as well and from he what could tell it is dual mass. Ultimatly I won't know until a pull the whole thing apart.

Rocky has brought in a kit that has a machined fly wheel and a Exedy clutch (with all the bearings). This is the first time he's brought it in so I'll be the first one of his customers to do it. It is a kit he's ordered from Austrialia and I know that the Aussies have allot of experience with our trucks. The nice thing about this kit is that it is a single mass fly wheel so I will be able to do future clutch replacements on this fly wheel.

If it turns out I have a single mass fly wheel then Jon will take the one he is shipping me back. I have to pay the shipping but I figure that it is a pretty reasonable offer none the less.

My thought is that I'm borrowing garage space to do this and I want all the parts there so I can get out of the borrowed garage as soon as possible.

I'll let people know how the install goes.
