Steve,
The fact that you even considered it for your car says it all to me .

Depends on the offset required for a Skylark, but the new style ones don't have as much room and 9x18s definitely DON'T, as Marty brought a set to Bedford to see if the offset was right and actually had to remove my calliper to get them on for the photos he took. He "thought" he could get the clearance with some different bells, so would require the wheel being sent to Hi-spec to ensure fitment (which is what I did with the Racing Hart wheels).
