Put a pic of my '44 Shirley and you can see the difference in the rear pad to yours, also why the different center screw on the front pad it seems bigger than the others.
Plus the rear ones are not flushed nor are they staked I thought it may help you to visualize the rear pads position and the set up of the screws flushed and staked.
I still feel for you and whats happened as that is very nice blonde furniture on the rifle I sincerely hope this story has a good ending for you..![]()
