My Suzuki is a 1983 SJ410 with a Nissan 1400 motor and five speed box. The only other mods are longer front suspension shackles and larger tyres (30 x 9.5x15's).
With time I hope to do more to it, to make it a real mud machine. The guys at work have named it the Blue Banana. There are two reasons for this, it is blue (original idea) and it is bent. The front end has had a hard life with some of the previous owners.
