John,
It would be great to see you out there with your Chevelle!
Got the sliders installed (thanks for the help jpop!). Here is Dale (welder) going at it:

Prime8, here are some dimensions for the passenger side ram mount:
Plate thickness 1/8" - I can't measure it very well because of the weld. It might be 3/16 but I doubt it. That plate is just welded flat onto the front face of the EVO bracket.
It is 8" long on the bottom and 6-1/2" on top. 2-1/4" high. Flush with the EVO bracket on the bottom and on the driver side.
The mounting tabs for the ram are made out of 1/4" steel. They are 2-3/4" long at the base, and the bolt hole center is 1-5/8 inches from the face. They are 3/4" between the two tabs for fitting the ram attachment in between.
There is a lot of adjustment in the ram for positioning left/right. It is up/down that is the more-critical measurement. I can't get in there to get an accurate measurement, but I think each would be a little different anyway. I recommend making the back plate without mounting tabs, then fitting it over the EVO bracket. Mark the hole for that 5/8" (?) bolt in the face of the EVO bracket. Cut that hole, then mount your new plate right on there. Mock up the ram in place above the tie rod and fit the mounting tabs wherever they need to go to make the ram level.
If you put the bolt through the mounting tabs / pass end of the ram, then tighten it up, they should all lock together so you can fit it wherever it needs to be. Then tack it in place.
PM me if you have any specific questions.
