Thanks. Well I've been thinking more on it and Am probably be going to hack the old fenders and reshape it. With something like this, everything is up in the air and nothing is set in stone as of yet, I just need a solid general plan of attach for this that is flexible to things changing as I move along with it.
I still have a while to figure things out so I just need some suggestions from everyone.
Yes I am planning to incorporate the whole assemblely (cut in half of course). I was planning to make whole new fenders when I ordered them but when I got them, they seemed alot more smaller than what I was expecting, so I might not need to make a whole new fender.
