Help w/fender placement 78 390

I need some help with the fender placement on my 1978 390. I'm restoring the bike. The rear fender that came off was not a husky fender, so I have no reference. Can somebody give me a measurement from the outside of the rear frame loop to the edge of the rear fender...like the pic I post here.. Also, some help with the splash guard placement?

What you are showing looks appropriate. If you have a brochure, I look at a good side view and make it look proportional.

Here is the 78 390 AMX

The horizontal line of the fender is even with the frame it's easy to line it up. The pic is correct.

If you need more pics - let me know

Distance from top of swing arm to bottom of splash guard:
