HAM7 SUS ready for doors

The HAM7 suspensions are good to go. I am only presenting the results for the OPO (in 89015), ZM1, ZM3, and ZM4 since those are the four suspensions that were adjusted/in the way of the HAM7 work.

I accidentally remeasured ZM4 (RyanC had already measured it after it was moved 88827), so I processed my measurement along with the others I did.
I had remeasured ZM4 instead of ZM3 when the ISI was stil locked, so I had to measure ZM3 with the ISI unlocked and DAMPED, but it didn't seem to affect the measurements. 

A before vs after comparison for these three ZMs(regular, zoomed) shows that they all look the same today as they did back in 2022.
