project Mary Jane Novak 5.3 mounts

I have a few things to say about these mounts they come nice look strong well we'll see they do use mostly existing holes but...the rear bolt I'm finding most haven't put in is in my op the most crucial but it's a pain the hole in the mount is off centered (I'm trying to figure out how to post pics on here )just a few pointers I'd like to share for anyone going this direction let me get the pic figure out if you need to know before ask
