I found my spare but it is broken. I may take it to my water jet pal to see if he can cut the raw shape (with the square) from a chunk of steel. One would then need a machinist to cut the rest of it. Be sort of high I bet.
Tom thanks for looking but I bet your right it might be pretty high. Thanks for the offer but I'll keep looking. I see I have another reply below also. Thanks again, Tracy
