Here is what you need:
1. Rallye Gauge Cluster and Bezel
2. Rallye Switch Cluster and Bezel
3. Rallye Light Bar (4 lights instead of 3)
Note: This is NOT interchangeable with non-rallye bar. Not Repopped
4. Rallye A/C Switch and Bezel
Note: Not Currently Repopped. The switch is SQUARE, whereas non-rallye has a "cut" corner. Bezel does not have an indention and it's smooth, not ribbed.
4. Rallye Radio DIN Bezel
Note: Only difference is that the Rallye bezel is smooth, not ribbed. Not Repopped either.
5. Rallye Cluster Wiring harness.
Note: A Correct wiring harness is repopped and avail from Year One, but is not necessary.
www.rt-eng.com makes a simple adapter harness to turn your non-rallye into a rallye harness. (Ask for Greg)
Greg at rt-eng.com also sells alot of the items you need.
As for price... if you have nothing expect to pay anywhere from $1000-1500 for correct stuff before you are all done.
Hope this helps! I have all my stuff together.... finally... but it took me a while.
