Turns out that the screw I recieved in the mail for copying purposes is far
too nice a screw to use. it may get lost,and the owner needs it back.It is
irreplaceable. I am sending it back. I want a rusty screw that I can keep.
I need to send a manufacturer a copy of the screw I need,and it may get
lost in all the shuffel. So I really need several rusty screws that I can
keep and wont be missed.

I have made about 50 or 60 phone calls. The 17mm truss head oem screw is
not avaliable anywhere. Period. Go Westy has a replacement pop top screw.It
is a common , off the shelf truss head screw . M6  with a 1.0 thread pitch
and a 14mm head. Standard issue for this size of screw.I need a 17mm truss
head and it is a oversized, oversize head and is,custom. VW has a
repacement screw thatGoWesty sells. It has a VW part number ,but is the
standard truss head of 14mm. Nothin special at all,and they crack the
fibergalss. . I need to get some made. Manufactures want orders of 100,00
to 250,00 to manufacture. If I find a manufacutere to do this ,price of
each screw will be high. I will have many thousand unsold screws,so this
must be aborbed in whatI can sell. I am still making calls ,but I have
little hope of getting a cheap screw. cannot give a esitmate,as I have no
estimate, myself.I see itthis way. 12 stainless steel screws that are
currently an eyesore, and take up lots of prime realestate on the vanagon
exterior. A major draw back to a nice looking van. YOu can add a washer
under the 12 screws,but thjat will look terriable.To get the correct issue,
it will cost some,but not out of line as to the immprovement it will make.
