I have (2) version 5/6 sti gauge clusters with the DCCD gauge on it. Both are in great physical form, but I do not know the currently mileage on them. One of them has a slight scratch you can see in the picture below.

These are plug and play into your 1999-2001 2.5RS and I believe the same for the non 2.5RS, but you should verify first.

$240 OBO shipped EA. Feel free to make a reasonable offer.
