Review: WELL BUILT - Well built for the price. I was surprised. They look to fit perfectly. I have yet to install yet. Going in a 81 C10
Review: Well Built. Fit great in my '81 k10. - You'll need to drill holes in brackets to mount spakers- as expected. I drilled a hole in the top tab to secure. Great product! Bought foam baffles to put behind (10$) 6x9s sound so much better now that they're not facing the back of my seat! Excellent value & product.

Mine came very nice. No flash rust or imperfections in the coating. Seem fairly solid. Installed easily using self taps. Not a super tight fit but fits well enough for a one size fits all product.
