QUestion about track systems

[Reel Chaos]

My new to me boat has Cisco fishing system tracks.  I have access to a very good fabricator but boat is currently wrapped. What size are the pieces that slide into the tracks? I want my fabricator to build me a rod tree

I have traxtech tracks on mine and just measured the bases for my great lakes systems rod trees.  The bottom plate that goes in the track is 5" long by 2-15/16" wide.  The top plate that rides on the track is 5"wide x 3-3/8" wide.

How thick is the part that slides into the track?

Both are a quarter inch thick
