Fortunately, looking at the VP service bulletins I found VP SB 1 and 2 that should be done before sealing in the fuselage. For SB #2, I ordered 1 1/4 inch 4130 steel from A/C Spruce and got some new hacksaw blades. They cut very easily and bent clean. For SB #1 I ordered the nuts bolts and washers but I'll do that install another time. Expenses listed for the nuts, bolts and 36" of 1 1/4" 4130 steel
