I bought those forks only for the lower fork lugs, damper rod and caps. The tubes, springs and seals are getting replaced with a racing bros lowering tube kit. The grom forks are about 3" too long stock. The kit replaces the upper and slider with shorter pieces to keep stock travel and be 3" shorter. But you need the fork cap, lugs and damper rod from the originals, or spend close to $1k for aftermarket. The dirty stock forks set me back $200.Nice, what's the deal with your fork tubes? Looks like new seals and a cleanup are in order...
