I love my 7330. 50# @ 28" Sweet shooter. However, there is a whole lot of shelf there. I put a thin (1/8" thick) piece of leather centered above the deepest part of the riser grip under the thin rug rest. Put same behind side plate and ran it down to the shelf leather. It tuned beautifully for me. It appears Phil did same with his; and, from catalog photos I've seen, his rest and sideplate looks pretty much like the original. Like mentioned above also, without that screw...you're out of business. Congrats on your find!
