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.
I am going to try the most forward holes on the tracks and put a spacer under the front two studs to 'lean back' a smidge as @Cuda Al suggested earlier.

If I go down the road of fabrication, you can get some inexpensive sliders and mount them on whatever type of riser you choose. I hesitate to go 'fixed' as .........ya never know......
