The 2 5/8 x 24 strip that goes on the bottom of F303 ( main spar bulkhead) is .032" material. My crate shipping inventory list does not account for F303F. Assuming it is to cut from bulk material, the only .032" stock to make it from is two sheets of 15 5/8 x 29 1/2. These look like very specific sizes for fabrication stock. So, where did your F303F strip come from ??
