Ah, glad to hear that they fit.
Adaptors for TR's 2 to 6 are all the same, covering widths from 4" to 5.5" and look to be the same as the new ones you have (apart from the PCD) -

The longer ones you started with are a bit of a puzzle, do they fit the splines on your wheels and do the same spinners fit both?
