I just ground through the front welds on the plate and bent it down just enough to slide it in. Took about 20 minutes. I'm going back out to weld it up now. It should be undetectable from original once done, except for that big sway bar being in there. Firm Feel has 2 available, I used the smaller of the two, which I believe is 1 1/8th". It's still significantly larger than the stock one.
