Inner Fender Replacement -'72 Valiant

I need to replace the inner fenders and rad support on my '72 Valiant. I have the inner fenders and rad support from another '72 but they are still attached to part of the frame rail and cowl. Here is a pic for a refresher as to why.



So, does anyone have pics/tutorials on how to replace them? Any special alignment issues I need to be aware of? Any tips, tricks, or advice that you can share would be greatly appreciated!
