I picked up my thermostat spacer and it does not have the recess in it to put the thermostat in on top of the spacer so I'll have to use a Chrsyler neck which has the recess for the thermostat. I have been looking online to find one that similar to mine but came up empty. Does anyone know which model of Chrysler and engine should I be looking for? Mine looks like the photo below.......thanks
