It was 4 bolts and 2 nuts. So not long. But it took me a day to Fab up the brackets. I thought about using the stock brackets.That looks great. How long does it take to remove the rear seat brackets and install your custom brackets. Did you try to make use of the stock brackets?
This guy gave me the idea, but in the end I didn't quite trust the T-nuts and fabbed brackets to bolt in place of the OEM seat brackets.
