Seats?

[Fletcher6371]

Ok i have a '71 C-10 and unfortunately i got the seat that has the springs and the foam instead of just the foam block, and everywhere i've looked i can't get the foam block i need. SO.... I'm looking for opinions on what kinda seat to put in it. I really like a 60/40 split but really don't know if it will fit. Any Ideas on a seat? and out of what. I've seen seats out of different trucks in mags and on-line put they never say what it's out of. (I've building a crusin' truck, not a 4x4 so a 5 gallon bucket won't work! i tested the brakes,tranny, engine, etc. of my truck on it and i think its time for an upgrade )
