Well if your looking for quality, my hoods probably fit the best out of any on the market. Most of the prep work is done prior to the master mold being built, and the fiberglass is handlaid with a smooth gel-coat applied, so any prep work afterwords is minimal. They also have the hinge & latch area steel reinforced. All the custom parts I make and sell, I also use on my cars, so quality is an issue as I am picky!
Who's ever hood you purchase, make sure and measure it from side to side, top to bottom at various locations to make sure it is the same as the original hoods, otherwise you may be in for a lot of work or big expense at the local body shop prior to paint.
