the truck 5.7 manifolds and the jeep I believe will fit tighter against the block and the outlets will point downward. The LX (car manifolds) stick out from the block further and dump the outlets directly at the firewall so they will not work unless you are going to run the exhaust into the car. Since I am running an RMS k frame I cannot say if any of them will give you issues with the torsion bars.
There are a couple running stock K frames and power steering with the borgeson power steering box and some slight modifications.
