Dave, if I remember correctly it comes from VANS with a close to 90 degree bend. My approach was to change the 90 degree bend into a radiused curve for the last 2" or so. I thne drilled it to the fuse and clecoed it.
I was going to rivet it, but in the end I decided that it will all fit better if I just pro sealed it on at the top/ bottom / rear. That appears to have worked well.
I can take a picture explicitly of it if that would help you.
Cheers, Steve.
