Removing Exterior Roll bars on a D90

[Vicious]

Hello -

I want take the exterior roll bars of my D90. Are the nuts on the other end of the bolts fixed? Please advise.

Thank you.

The interior parts of the roll cage have retaining nuts welded to the brackets.
Hope this helps

You're going to end up with a rectangular hole in the upper rear corner of each of the wing tops. The bolts holding that portion of the cage go into brackets bolted vertically to the bulkhead and sandwich the vertical edge of the wings. Those nuts are welded to the brackets also. You should probably leave those brackets in place and fashion a cover plate, or you'll have a big hole looking straight down to the ground. (Or were you only temporarily removing the cage?)
