I have a super low mile NCRS 95 LT1 ZF6, I need a little help. Where can I find the current correct Bilstein part #'s for the shocks? Rock Auto shows front with Z51 and rear without Z51 (no others). I would like to upgrade to Z51/z07 shocks but FE1 are fine too. I just want a matched set. THEN who is the current Bilstein rebuilder and do you know if they do cosmetic restoration as well ( I have some Bilstein OE stickers if needed but not 100% NCRS). Any and all help would be appreciated. No FX3. Car rides fantastic but they are 25 years old, no leaks. Plus would like shiny new shocks, will put oems back on for flight judging.
