advice on speaker placement

[AC72]

72 c20. just put in stereo, 5 1/4 in doors (cut by po). where to put some 6x9s? put in a set of buckets from a 98 chevy truck, but i don't know if they are staying in. feel like i am sitting too high and too close to st. wheel. the tank is still in the cab, and i have no imidiate plans to relocate it, although that would solve a lot of problems. So if the stay in, i will build a box to put between them, but if i put the bench back in, where can i put the speakers? i could make kick panels, but it seems they may be in the way. any ideas? any kick panel plans you guys have out there? a pattern would be nice, im no carpenter! let me know what y'all did, give me some ideas............thanks.
