Can I modify the seat adjusters to go farther back?

I mounted my RX7 seats on hardwood sticks, which elevated them enough to where I liked them to be, then I set the recline by washering up the front , then I moved them back to where my clutch foot was happy, then I installed a small-diameter low-dish, fat-rimmed, aftermarket steering wheel, to get it off mabelly.
I mean that stock steering wheel was hopelessly huge.
and the RX7 seats were hoplessly low.
and the end-result was fabulous.
