With the seats in hand, I could have my New Hampshire cage builder build to the negotiated requests. We used the M2 CS rear cage section as a reference and made tweaks for my particular needs:
- Zero degree angle from harness bar to neck restraint when seated. I could not achieve this with any bolt in offerings.
- Cross bars low to not obstruct my rear view.
- Weld in to the same front locations as the M2 CS.
- Weld to the lower floor (reinforced) and not the rear wheel well for strength; a better connection through the rear frame mount point area.
- Tabs for mounting equipment for future projects.
- Durable painted finish instead of powder coat in case I need to do touchup.
I got the car back, re-installed the removed interior pieces and then installed the harnesses, split collars and roll bar pads (all not shown). With this, all of my needs are met.
