heh, its really not that easy making a braket that has proper seat tilt, side height level all thrown into keeping a low profile. I was going to make brackets for my momo seat before i sold it. I mocked the chair up in the car. Took some accurate floor measurements from a common reference point. I put about 4 hours into drawing, thinking, making, scraping, revising, bending some flat bar into brakets that would have worked if i was 5'5" tall. The location was slightly off, seat wasnt 1000% strait, slightly tilted towards teh console. The only thing that i had right was the amount of recline that i wanted in the bucket. Take my experiance with a grain of salt, but im pretty sure you will be hard pressed not to get an astronomical price from someone altering seat brakets to your satisfication. I wish you lots of good luck if you venture into this fabrication your self, you will need it.
the whole thing gets thrown off because the 4 mounts are on different x and y axis.
have fun
