Rear side trunk dimensions for meth tanks?

Getting ready to take delivery of my M235i in the next week or so and would like to know if anyone has or can take some measurements inside the trunk for me. In my previous E82 and E92, there were a couple areas in the trunk that one could mount a meth tank. Wondering if there is sufficient space in those same areas in the F22 as well. I meant to check it out when originally test drove the M235i but completely forgot to, lol. The areas I'm referring to are outlined in the pic below. I'm pretty set on these two areas because I utilize my trunk quite often and normal floor mounted tanks would be in the way more often than not.

For reference, a standard 4qt meth tank is 9.85" H x 8.6" W x 4.2" L

Thanks in advance!! :party0030:
