A few changes that I know of mate,
Series 1 R32= blue face instrument cluster, RB on timing case, silver GT badge on side, steering wheel (not sure)
Series 2 r32+= grey face cluster, no RB on timing case, red/white GT badge like R33, R33 style steering wheel, also interior plastic like dash (rippled orange peel look)
Cheers
Anyone know anything about 60th anniversary r32?
