Looks very nice Ross.
If you don't know when the belts were last changed, change them right away. Replace them with the later kevlar belts which have red writing rather than white.
Same goes for the fuel filter and the oil obviously.
Check the wiring from the alternator to the regulator and on to the battery. The wiring is too thin as standard and the connectors are poor. The connectors can overheat and melt the insulation off the wiring and short the regulator.
The rear suspension was pretty worn on mine. Needed new needle rollers and rose joints.
Apart from that it should be fine
Enloy it.
