thors are .495 at the thinnest end but the skirt is flared to the size that you need. .500" is the smallest and it wont fit any of my older tighter bored cva's.
I havent seen a tc as of yet that took anything smaller than the .502" thor. And thats really odd.
You could give the .500 thor a try but get ready to either use a mallet and SS rod to seat it or push it back out.
