hello, was looking for correct setup. i have 10/76 2F engine in 1977 FJ40, and am adding vintage air and mini- truck power steering, i notice that my harmonic balancer, crank pulley only has 1 V groove. Can somebody help with the correct answer to set up with 2 belts. I know i will need to find an 2 V groove crank pulley balancer, does anyone know where i can find one? also what should run in rear V groove and what should run in front V groove?
