aftermarket seats and brackets

can anyone tell me if i will need to build my own custom brackets so i cab fit a pair of sparco seats in my 1991 nissan 240sx.........the hump in the floor and the side mounts are the reason im asking this.

ask the place you're buying the seats from.. if they don't know then call sparco and ask. they'll be able to tell you.
if you already have the seats you should be able to figure that out yourself

JIC makes a seat bracket that mounts in the center so it misses the hump SCC had a article on it for there project 240

oh another problem w/ aftermarket seats in the 240 is head room

I thought aftermarket seats were lower.
