I’ve heard of the th400 but never have seen one. I know it’s not a th350Looks like a TH400,I see what looks like the vacuum modulator on the right front side ..no madulator on a 700R4,a TH350's modulator is on the right rear side,next to the tail housing.
#6 oil filter canister
#9-10...maybe fender to core support, or fender to front grille valance.
