the rear mounting bolts on my sparco evo XL's was a fun time as well. the bottom of the seat is about 1/2" above the bolts... so you have to tighten just enough so you can adjust the mounts to mount the seat to the mounts, and then use and open ended wrench to torque the hex bolts down. like stated, oem bolts won't work because you can't get a torx bit on it.
tightening the inboard rear bolt is a real treat as well.
