The answer to your problems

This product was shipped promptly (I paid extra for next day) and arrived on time. A customer's Jeep needed this repair I noticed while in for some other work. At first I was a bit skeptical of the fitment, but even more wary at the idea of building a piece like this from scratch. I ordered it and was extremely impressed with the fitment on this product. Following the instructions, I notched the frame, eliminating all of the old rotted out material. Removing the inner fender liner made quick work of the entire thing. Can't beat supporting family owned businesses, and my neighbors over the state line in Ohio. Will recommend/buy again if ever needed. Thanks for a great product!

Quality

Excellent part for frame repair. Bought this one but after the frame repair guy told me I had bought the better part that they like seeing brought to the shop, I ended up ordering the other side even though I could have lived without it. Might as well do them both. They have plenty of meat. I was a welder fitter in my younger days and I could tell when they arrived they were built correctly and the welds had excellent penetration. Great product made by Rust Buster.
