I got a 12cm on a 92 and was wondering if there is a gasket that goes on the back of the turbo to the exaust plate? where the 5 or so bolts are at.

 

you can reuse the gasket there if you still have it. I just did the same thing and used some hi temp rtv and it hasen't burned out yet. The only time you would see some real pressure there is if you have a exhaust brake. good luck

I dont have the gasket and the dodge dealer says there is not one one his computer.

 

Thats what they told me too. I would try a cummins dealer. Its worth a try. or you could make a gasket out of tin flashing or maybe some sheet copper. just some ideas! Good luck
