Attached is picture of the adjusters from the other head I have and the one that is from the 38 engine. The one with the flat looking top is the one from the 38. The other 3 don't have that flat spot? I'm going to look at the othe ones in a few days as I'm also working on getting the new springs in the 49. One more part to come yet. Supposed to be tomorrow. The 3rd picture is the bottom of the bad pushrod.
