thread size on the RH muffler hanger bracket

Steve, I made one of the RH muffler stud brackets from memory. I had an original for my 67. It's still in the shop somewhere on one of the shelves. I just couldent find it to copy it. Being your kind of the expert, Is this close? I remember the other one having a clipped corner for pan clearance. Its hidden under the seat so I guess it doesnt matter. Just kinda curious how well I did from memory having last handled and looked at that original bracket probably 4 years ago.
