Are all SF "C" style tail caps the same internal length? I need five more millimeters inside one of my FM 2 x 18650 C head/tail body tubes and am wondering if there is a switch or tail cap that offers a little more room than the standard Z41. The tube holds 5 x 2/3A and works great. I'm just concerned that I'm forcing things a bit. I'll save the spring cutting for a last resort.
Thank you!
