on page 8-5 of my instructions, under AFT FUSELAGE ASSEMBLY,2/3 rds down, it says, "Drill all of the remaining
holes (execpt the ones for the F-706 bulkhead etc etc. what holes do u not drill on bulkhead f-706?
the Aft fuse gets joined to the center fuse soon, and the side skins go on. This is when you match drill F706. If you go ahead and match drill/dimple F706 now, it will be difficult to get a good aft/ center fuse alignment.
You will find that you can get at F706 to dimple easy after you remove the joined sections later on.
