Yeah. Some minor differences, piston, piston head, spring, spring guide, but in terms of getting a Titan working in there, your only obstacle is the sector gear.Think there might be other differences in the box but have never tried it personally. I do have a v3 chimera to remove from a box so will look into it.
I spoke to Gate a while back and they said they were looking at doing one.
Must depend who you speak to and when I guess. I’d love it if they did release a Titan for that gearbox
