Power Meter With Giant TCR

Anyone running a left only crank power meter with a Giant TCR?

Considering getting a power meter for an Advanced Pro 1 2019 & the frame clearance looks awfully tight for the 4iiii especially. Not so much but still tight for the Stages.

I have a Wahoo cadence sensor at the minute & that just about (barely) fits.

The pod seems quite a bit bigger on the 4iiii than the Stages, anyone confirm that?

TIA.
