I looked everywhere and people say it CAN fit but you have to cut everything to shreds, break things, drill things, make things, eventually it kinda works for SOME people....hmm that sounds silly to me. The most recent thread I saw said if you cut off all tabs you can "just force it in there and the pressure holds it....." C'mon that's just half-baked I say! So, 4 easy steps to glory (note I am not addressing wiring, those threads already exist) 1. Take your GD cluster and cut the tabs on either side of the cluster about 1/8" in from the outer edge. As a guide cut right up to the main circular hole with a ever so slight angle canting the top out. 2. Cut off the lower alignment pins on the dash where the old cluster lined up (similar to where the GD cluster lower holes are but not the same. 3. Push the dang thing in there and your done with the actual cluster, and you can STILL use the top bolt to secure! Yay! Alternatively you can also drill two tiny holes where those alignment plastic pins where using the GD lower tabs as guide and secure with small screws. 4. Trim cluster plastic surround to fit as preferred! Some people trim about 2" off the back side, basically up to the two vertical bolt holes that service the surround in. Done! I was so surprised this doesn't exist anywhere on RS25 or Nasioc but alas it does not. Bonus: if you ever part your car out this is still usable for other cars as you have not removed any mounting points from the cluster!
