when i ordered mine, nick from DT told me there was a new one being disigned that bolted in to replace the rubber mounted type,so i held off.
the flying scott is right, to get the best it MUST to bolted structurally to the car.that rubber shock/swivel mount will have way to much play in it.rubber mount to brace to rubber mount again? you could measure that play with a ruler.
as for your question the part numbers havent changed,sorry.
