On a 1995 bike, the oil was put in the shock in the summer of 1994. Add 15 years to that date and what do you get? Today. Unless you know better, assume it is 15 years old. Well, the drops that are still trapped inside and haven't leaked out yet.
Please just buy a 1995+ KDX shock and pay someone to rebuild it. Trying to match up a shock from another bike is going to be a headache. It's valved wrong, sprung wrong, shaft length, it could be worn out too, wrong shock length, etc.
Rechroming is $125 - 200 including shipping both ways, besides all the other rebuild parts you would still need. Any suspension shop is almost always going to send the shaft out and not do it in house.
After buying a used shock and paying for shipping both ways, parts and labor, you are looking at, at least $200.
