Fit a 78 GMC 1500 2 wheel drive inside of the frame
Fit well on my 78 GMC 1500. I did have to trim some of the top and bottom, but I was able to get it inside of the frame rather than the outside. This provides significantly more support and don't have to worry about the steering box not aligning, additionally it will prevent future cracks. The bolt holes were inconsistent and had to re-drill two of them since they were too small for my steering box bolts. Overall good product and will support the steering box. Pics I've attached are before welding.

Worked great
1986 K10 pickup, frame was cracked by the stock steering box over the years. Had a shop weld this thing in place, and it should hold up well - nice and sturdy!

Modified to fit inside frame
I have an 86 Chevy plow truck and the frame broke at the steering box. It now has two of these brackets modified to sit inside and outside on the frame.

Works for 1/2 ton 2wd with some modifications.
I like the fitment on the Rough Country plates more than the previous plates I’ve ordered in the past.
