Pertaining to an '87 Westfalia with chrome bumpers:

Can anyone tell me if it is necessary to first remove the bumper in
order to replace the plastic end caps on it?

I can't see how to get at the 13mm nut that holds the cap onto the
bumper bar without first removing the bumper.

Please reply via p-mail, as I'm in Digest Mode.

Thanx,

Dan
