FYI - I wanted to keep my original OEM front calipers and the stamped Nissan logo (all nicely painted too). I found it cheaper to get remanufactured calipers rather than buy a rebuild kit. Swapped the parts and then returned the car store calipers with old pistons and seals for the core deposit refund. I'm plan to do the same for my rear caliper rebuild coming up soon - although rebuild pistons might price out cheaper since the piston count is half of the fronts.
