Step 02: AS shown in Figure 2, make the F-1236B-L & R Outbd Step Attach Angles by trimming the flanges of the two angles separated in Step 1. ( At this point these two parts are identical, but will become left and right once they are drilled in a later step.
The two, remaining, untrimmed angles separated in Step 1 are designated F-1236A-L & R Inbd Step Attached Angles.

Step 05: Cleco the 1236A-L Inbd Step Attach Angle to the F-1212-R Step Rib and the the F-1236B-L Outbd Step Attach Angle to the F-1212-L Step Rib as shown in Figure 4, then match drill #30 the indicated holes of the F-1202F Bulkhead in to the step attach angles.
Cleco the holes, then repeat this step for the right side of the fuselage.		  
Step 06: Final-Drill 1/4" the hole in the F-1202F Bulkhead and F-1236B-L Outbd Step Attach Angle that is indicated in Figure 5.  
Step 07: Temporarily bolt the WD-1233-L Step to the F1202F Bulkhead and F_1236B-L Outbd Step attach Angle.  
Step 08: Make the pad of the WD-1233-L horizontal, however, the inbd, top corner of the step is to remain even with or below the beginning  of the radius of the F1202F Bulkhead. See Figure 5. Once the step is positioned, match-drill 1/4" the inboard hole of the step into the bulkhead and F-1236A-L inbd Step Attach Angle. Remove the step.  
Step 09: Seal the opening ( see Figure 5 ) in the WD-1233L Step with fuel tank sealant.  
Step 10: Repeat Steps 6 through 9 for the right side of the fuselage using the WD-1233-R Step.

Builder Note: adjust step until string across the top of the steps is parallel to the F-1202F Bulkhead.
