Don't know the PN on that but I had that happen in my '88 Shadow one day, luckily the plug just landed on the inlet tube from the turbo to the intake. I've talked to somebody who nearly lost the motor in his that way! Funny thing is that the plug on my '85 Lebaron GTS turbo was held in by some plastic piece that bolted to the head with I think three or four bolts (sorry, no pics the car is long gone :bawl: ). I don't know if you can still find the plugs or that plastic piece new at a dealer, but that would be the best way to go for the plug. I would check to see if your head has the holes around that spot tapped for bolts and hit the boneyard for that cover, it may help of that happens again. The 2.2/2.5 has no relation to the 2.5/4.0 other than being inline motors and 3 out of the 4 have been offered in the Dakota at somepoint in the first three "generations" of production.
