Added JIS#1 and JIS#2 screwdrivers to my McMaster Carr cart with the 1/4 ID static port washers and placed the order. It took 16 minutes before I received a shipping notification. Wow. Worked on positioning the parts with a 0.130" spacer plus a 0.062" washer. Didn't like the way some things were turning out. Researched Crow harnesses and crotch strap mounts on vansairforce. Found Crow made a change in 2018/2019 that allowed it to work with the Van's mount without some of the previous modifications. Decided to just use a 0.130" spacer. Was having difficulty with placing the mounting brackets to they would align with holes in the seat pan. Figured out what I hoped to be a better solution. Marked the fore/aft mark on the top of the ribs based on measurements from the seat pan screw holes to the seat pan pilot holes for the screws to the mounting bracket. That allowed me to mark the centerline of the mounting bracket flange, alight it to the fore aft mark, adjust fore/aft tilt with a 90 degree angle against the fuselage bottom skin and clamp the clamp the F7117B mounting bracket flanges for drilling. Used an air 90 degree drill with a #30 bit. Drilled one mounting bracket flange to rib hole and held it in place using a cleco. Checked alignment and continued adding holes/clecos to the same flange. Rolled the fuselage over 180 degrees and checked, clamped and drilled and clecoed the other flange. I' really happy about how it turned out. Taped spacer blocks to the F7117B bracket and positioned and checked the F7117A bracket alignment. It is almost ready to be drilled to the rib.
