chain guard

I have tried zip ties but on the chain guard where the hole is, it is too far back behind the frame where I am supposed to tie it down. I can upload pictures if needed... What should I do to try and fix this? Or are there any other chain guard alternatives? I want to be safe, I have been riding...

Meet "Patience"........ I picked this JC Higgins up at an antique barn near our house for $45.oo for 2-years I've been stashing this frame deeper and deeper behind stuff at the barn then my Wife snuck up behind me the last time and said "If you aren't going to buy it quit hiding it" well...
