First off, nice car you got going. Looking good
Second, any chance the car may have been repaired after an accident at some point in it's life? Just curious as the amount of fabbing you had to do to get the HDK in there seems excessive to me.
Also, in regards to the inner fender crushing down 3/16ths of an inch, could you have sourced longer bolts and maybe shimmed it to help prevent that? Not sure I like the idea of my inner fender crushing that far.
