Does anybody know the official dimensions of the bolt hole pattern on the frame rail for our fuel tank hangers? I have a new set of fuel tank hangers, but the replacement ones do not have the weld nuts on the brackets. I want to get some square, weld nuts and put them on my brackets and I was going to make a fixture so that they are aligned perfectly. A little anal retentive I know, but it makes hanging the fuel tanks so much easier.

Stuck a tape on the back bracket pattern on my frame last night. The back pattern looks like it is 4-1/2" Wide x 4-1/4" Tall. The front pattern is a little more tricky to measure with a tape as it is staggered, but looks to be also 4-1/2" Wide.
