As you all may remember, I am in the process of rehabilitating a '48 Kaiser. One of the parts that I had searched for and wasn't able to find was a thermostat housing specifically for a Kaiser or Frazer. Kaiser Willys Auto Supply has used ones that fit the 6-226 engine so I ordered one. Much to my dismay, the "ears" for mounting were too thick and there was no way the bolts in my already installed head would work. After pondering this conundrum, I decided to modify the ears in order to make them thinner. Using a 4 1/2" angle grinder with a cut off wheel, I was able to cut horizontally to the neck of the housing then vertically along the neck of the housing. Use caution that you don't cut too deep towards the neck when cutting towards it! When cutting downwards along the neck, make sure to keep your wheel parallel to the neck's axis or you may find you've cut too deeply. A final dressing with a grinding wheel and it was ready for painting. I wanted to share this in case anyone else had the same problem, I hope it helps. I have pics of how mine turned out but wasn't able to post them here : (
