Take seat out of car.
Use spacers & long bolts were seat is attach to the rails.
put seat back in car.
Use small Steel Pipe or other hard things as spacers. Square blocks of Metal or Some Plastic types w/ holes drilled thru is likely better then pipes. (Nylon, Delrin, & other very tough plastic won't compress etc.)
But note that higher seat(s) can likely will cause problems w/ the Seat Belts.
Example: You can't simply move the SB Latch because the bolt goes into reinforce hole in the "tunnel" over gas tank.
Lap & upper belts is made for factory seat design too & may not work right in a wreck if you raise them too much.
May cause problems w/ the pedals too just because the angle of feet & legs even if can reach them @ all.
⚠️ Warning: This type mods may cause legal problems. Many "Handicap" aids/mods many require you to have script from doctor or related, required relearning by certified trainer, retest to drive, restrictions on your license & more just to install them.
I've been dealing w/ many "Handicap" aids/mods for decades. If done wrong or missing doc's etc, is often 10 to 100 times worse in & after a wreck for dealing Insurance & in court(s) that's if you survive w/ junk mods.
Example: they make various pedal extensions but need a script to buy/install etc.
Also, The "Norms" can't drive w/ many mods either can cause problems when you go to mechanic, inspection in some states, some parking like Valet Parking, etc. because can't fit or other problems.
Some aids can even be a Ticket w/ cops stopping "Norms" driving w/ your equipment.
Is big reason why many have to remove or disable their aids for anyone else to drive.

Dr. Ian Malcolm: Yeah, but your scientists were so preoccupied with whether or not they could, they didn't stop to think if they should.
