I'm selling my 1984 Delta 88 spoke hubcaps either 15 inch or 16 inch in size with a 5 bolt pattern. The buyer has an 89 Cutlass Ciera with a tire of 185-75-14. Is it possible to take a 15 inch 5 bolt pattern hubcap and fit it to a 14 inch 5 bolt pattern?

Don't think... the Cierra is a front wheel drive with positive offset wheels and the Delta 88 isn't.. with negative offset wheels...

15 inch hubcaps will not fit on 14 inch wheels.
