Started as an RB 30 auto VL and with body kit and paint etc now a genuine replica walky. Fitting a VT 304 roller cam motor and 4 speed auto, very difficult to convert wiring from RB30 to VT. Not much detailed wiring diagrams on-line, had to work it out one circuit at a time. The transmission tunnel was so tight and had to do a bit of persuading to clear oil cooler fittings etc.
