My friend just bought an RJ70 and is replacing the alternator. (DIRECT FIT HIGH OUTPUT ALTERNATOR 140 AMP 1985-1992 22R/22RE TRUCK & 4RUNNER) He is looking at installing the Fast Pro ignition iit 20R/22R (CARBURETED APPLICATIONS ONLY). Anyone done this or have any suggestions? (anyone else even have an RJ70?)
