First of all you need to know the brand and model of your adjustable absorber, then look for shops that does adjustable absorber service and repair, mainly for aftermarket japan adjustable absorber, i use to have a contact that i can pass u, but i lost my phone, give me some time, i'll pm u the number later, shop is at sri kembangan serdang. I have a front pair konged s13 adjustable absorber, Tein HR with springs and pillow ball mount, the travelling piston died already, if the 1 you got from the halfcut are from Tein, then i can sell mine cheap cheap to u.
