I haven't bought a repo hood in 25 years and as I recall, the fit and quality were very good. The only problem I encountered versus original hoods was the clearance between the top panels and the hinges being too narrow. If you have primered the panels and painted with some kind of enamel, the top panels scrape the paint off the hinges when the hood is opened. On the other hand, lacquer is much thinner than enamel, so if you use lacquer on the hood, this might not be a problem. But depending upon where you live, lacquer may no longer be available. Plan accordingly.
While the hood was still disassembled from the manufacturer and the top panels were still separated, I used to draw a line on the top panels slightly towards the outboard side, leaving maybe 1/32nd or 1/64th of an inch of exposed metal on the inboard side where the hinge from the opposite side panel meets. Then I would take a small file and file away that exposed area to create a wider gap so that opening hood panel would not be scraped by the hinge with its thick enamel paint. The increased gap will not be noticeable. I tried spraying less paint in this area, with the predictable poor results. Since I exclusively spray PPG Concept (until it completely goes away), this is how I will continue to prepare any repo hoods that I am obliged to paint.
