I would prefer to run series 2/3 everything.

What can change is the caster with incorrect mix/match of the various series.

Both RMC and g-force originally suffered from light, vague steering and would not self center. The solution was to move the top control arms back to increase the caster. Note how your top arm is bolted behind the centerline of the chassis cross tube. Originally the arms were in line with that cross tube. ( leastwise it was with the RMC.)

Caster is not a critical issue when compared with other front end settings. In fact caster in modern cars has increased progressively as power steering has become standard fitment. My fairlane on full lock would almost lay the front tyres on their side.

Your G-force has heaps of caster and it is for that reason I'd prefer the series 2/3 components. But.....the series 1 components could be used if you found the steering heavy as they are offset so could reduce caster by moving the arms front to back.

Confused yet?
