Rear suspension mount measurements

[aesthetect]

I have been bouncing between a couple different options for an EV setup using an 818 chassis and I unfortunately have to ask for some help from some kind strangers in order to get to the next stage of planning/decision making.

Hoping someone could please give me an accurate measure of some of the rear suspension mount dimensions. The blue is the key question. Either bolt center to bolt center or room for clearance inside is fine (just please tell me which). If not a problem to measure the orange then that is even more appreciated.

THANK YOU IN ADVANCE!
