I like the look of the bumpers too.
Have them on my 87 Wolfsburg.

and the right tire in 14 inch for the right look would be 205/70 R 14
........
in a vanagon-rated tire of course.

if you ever get a chance to get 87 and later Wolfsburg or Carat Springs ..
they're about 1/2 inch lower....
makes the whole van look pretty neat, and not too low.
Goes really nicely with the bumpers.

I haven't had my front fiberglass bumper  off for a while..
but I'm pretty sure besides the 'side bolt-on'  brackets..
here are a couple that are welded to the top or front of  the front 'metal
bumper' ...the one you don't see.

that may not be exactly right ..but I do remember noticing something on my
87 Wolfsburg and thinking, to put this bumper on the front where a metal one
was ......some fabrication reqr'd.

Hi all

My 87 GL has just been painted and I am going to install Fiberglass Front
and Rear Bumpers and the Front AirDam.  I know there are a lot of stronger
bumpers out there but I really love the look.  Anyways, I am trying to find
the correct hardware list for the bumpers and Air Dam.  I looked in Bentley
and online hoping to find the hardware list.  Does any know of anyone that
sells the correct Bumper and Air Dam hardware? or where I can get a list of
what is needed?  The Body Shop that did all the work does not specialize in
VWs so if I can provide them the proper hardware, installation will go
smoothly and it will still be Genuine.  I have given up trying to find new
alloys so I am going to run with the original 14".  I am wondering what size
tire would fill the wheel wells to get the proper look.  My Van will not be
doing any off-roading,

Thanks again in advance for your help
