Will a Vortx with the standard nosecone take the newer chunky grill nose or does anything else need to be changed?

No, the newer nose is higher, and that takes into account the taller side bodywork, different shape bonnet and scuttle.

I had the choice when mine was in for, ahem 'rework' when a new body set was being ordered...

so what did you go for when ordering?

Old style, thats my preference

New nosecone can be made for either height bodywork (mine is the lower one), but you do need bonnet & scuttle changed as well.
