Brief Description: Clecoed top skin for marking the roll bar drilling
Clecoed top front skin on to ribs ,attach angles after a goo fit I measured and installed WD-641 roll bar adjusted to vertical 90 degrees frm 0 degrees leval on F-721 L/R per DWG 42. After clamping down with bolts in the Roll bar& drilling both F-121D L/R attach angles. I clamped all down then removed top skin to finish driling the WD 643 rolll bar brace.
