o2 senser location bank one

[93silverado]

have check engine light had scan showed o2 senser bk one they said on the right side and as engine sits in ther sideways which is bank one front or the back of engine . I'm pretty sure with my luck it will be the one by the firewall as ther seems to be about a half an inch of space to work in. thanks for any help 93

Yes, bank 1 is the firewall side, but the HEGO sensor is not hard to replace from below.
