When I had a Heckler ’06 model, I’m 99% sure the shock size was 200×57 as I swapped the shocks over from my Meta 6.6 which was the same.
According the S/C site:
“What size shock does the Heckler use?
8.5” x 2.5” (216x 63mm)
The mounting hardware is 22mm wide with an 8mm through hole.”
What size shock does the Nomad use?
8.5” x 2.5” (216x 63mm)
The mounting hardware is 22mm (21.8mm for rockshox products) wide with an 8mm through hole.
