Andy, a few other things:
You will probably will have to replace your oil lines. As you can see in Charlie's picture (Maybe didn't notice.) The old style exhaust has the cross over pipe that crosses in the front of the motor instead of the back.
(It's the shiney pipe you can see below the engine stand adapter and between the two heat exchangers. There is another line that connects to the end of this one and then goes to the extermnal thermostst in the front of the right rear fender well. When you get to that piont ask for help because sometimes they are a bitch to get off.

Another small project that goes along with this is connecting the air hose at the rear of the heat exchanger up to the air hoses comming from the heater fan if you still have one or the takeoffs. I think there are a few variations of this depending on the year and the engine tin.

I ended up using one of the elbows that came off the old heat exchangers and modifying it a little.

Let us know what you find out about current prices.
I doubt you will find them locally and if you do there will be a premium.
On the other hand you might compaire that to shipping and don't forget about sales tax.

I ordered mine thru vertex. The SSI's came right from SSI's wharehouse and the muffler from vertex.

Good luck! If you need help with the exhaust studs let us know.
The tools and the talent are on this board.
