i have the tunnel extension from tracks usa and put it on a viper and mounted a cooler . yes there was some fab work and customising. it looks awesome and i posted a while ago about where you can get the hose covers for real cheap and they are the same as factory. i can see if i can find the old pics since sled is in storage. but the pics are before all ends cleaned up and then polished. now i have the correct hoses and hose covers. and it looks factory if you ask me. but i would just buy the kit next time that has everything and not screw around with it.
