Side fender emblem mount

[easyrider]

I ended up replacing my front fenders with after market fenders and after installing fenders/ inner fender I noticed there wasn't any holes in the fenders for the C-10 bowtie and upon further inspection after fender installed, there is no access to back of fenders to put nuts on emblem if there were holes to install emblems !
So, I really don't want to take fenders and inner fenders back off. It was a bugger getting holes to line up in the process.
I remember on one car I had the emblems were held on with metal inserts that fit into hole and emblems push fit into them. I can't remember what car they were on though.
Any ideas what would be easiest way to make this work out? I'm sure this isn't the only time someone had this happen. I do want my side emblems on fenders.
Any help or information will be greatly appreciated....Thanks!!
