Well that bracket isn't bolted to anything because .......? it's bolted in 8
other places, mine doesn't budge a millimeter the way it is, I've seen other
people leaving this bracket off. no i won't jump off a cliff if they do
though! :)
Are you thinking it has an effect on my issue or are you just pointing out
the obvious for me? :)
I'm also familiar with the complete idiots guide from when I owned a 1967
beetle. I thought it was a good read, comical and whatnot with
some philosophical insight into life. Didn't know it would be very
applicable to a 1991 Vanagon. I should pick up another one just to have
around, if for nothing more than the cover.
peace,
