Does anyone know where these can be found? I managed to lose one of mine last weekend. My experience with other engines is that they're not something you'll find at the hardware store. I may go to a boneyard tomorrow and pull one out of a wreck but I wanted to know if they can be more easily had elsewhere. I'd like to try to start this engine tomorrow, if possible. If I do pull one out of a wreck, will any 235 do? My truck is a 56 1/2 ton.
