1967 barracuda bucket seat adjust

Still need to install my buckets, but I've been trying to get the right tracks at a reasonable cost. I'm also tall and would like the seat to go farther back/lower. Since I'm the only one that drives my car, I've thought about just making some fixed "tracks" out of square tubing and drilling holes where they fit best for me. Maybe even slotting the holes so there is some adjustablity with a wrench.
