Kit parts direct do a pair of e marked indicators for 14 quid. They are 17cm long so extend well past the IVA limit when bolted through holes in the nose cone. As the Saturn nose cone does not have any flat surface to bolt them to I made little wedges that sandwich between the indicator stem and the nose cone so the indicators were level, a drop of black polyurethane neatened the edges up.
It seemed easier to me than having to make extensions, although I will say they are a bit on the large side and give a more "traditional" look. I quite like that look as I am an old git, you young whippersnappers may think differently
Best and all that,
Enoch
