Sorry I haven’t been on in a while, my iPad died and took my info with it. I have a 2003 Dixon ZTR 4423 model # #28Q777 and measurements the C- Gage

[dlp571@frontier.com]

The “C”- Gage is made from 3/32” plate Steel, it’s outside dimensions is 3-9/16” tall X 1” wide vertical back, at the top and bottom of what you called the C-Gage, the top of the “C” and at the bottom the outside overall measurement is 3-9/16” X 2” wide, the two branches are 1/2” tall X 1” long, with the gap between the top and bottom 2-9/16” or the Gage area. If you still need these measurements, if needed I can get my mic out, but it will be the same, hope it helps
