Center console question

I'll try to get measurements tonight, right now I only have privacy in bathroom, wife watching every move. The angle might be tricky, for me anyway, not good at fabbing. Looks like all holes same size, there are two on each end. I think maybe the bolts in there now go to the stick. I have that too, somewhere. But, maybe use 1/8" for mockup to see how it fits? I can copy anything-Monkey See,Monkey Do.
