Been a long week but got everything completely stripped and got some epoxy primer layed down on all the metal surfaces. have plenty of body work to do but atleast its sealed and protected now. Hopefully in the next week or two i can get the bodywork done and get some color on it.
I did talk to john and his comment is "I don’t claim to be an expert on bonding. But in my experience cracking at a bond line is often due to inadequate surface prep both the underside of the fiberglass and the underlying metal), poor bonding agent, not enough bonding agent, cheap body filler, and/or excessive flexing of the unibody. On the other hand, I know a lot of guys who do the bolt-on installation. For performance applications, it can be an advantage for working inside the wheel well".
With that said I think I will spend the time to make the fitment as good as possible and make a last minute decision based on how well it fits/looks.
