Wheres My O2 Sensors B20A7? / Clutch Judder

I have a 1991 UK 2.0i 16V BA20A7 4WS car. After reading the tune up section on and reading the Honda Workshop Manual I asked my local garage to change my oxygen sensors. I know my car doesnt have a Cat so my model has them in the manifold behind the heatshield?
They told me it doesnt have them. I argued with the mechanic because I have seen everyone elses photos and read about all of your cars. I have the car back now but I cant find them! Is the BA20A7 different?

The car runs ok and only has 59K on the clock but I do get some clutch judder. The clutch seems worse at low speeds in first & 2nd Gear especialy on a hill start. Should I get a new flywheel and clutch fitted or will a standard clutch kit be ok?

You should have 2 o2 sensors like in the pic's located in the exhaust manifold towards the bottom. B20a7 shouldn't have any EGR devices as well...

Your clutch jidder could be tied into your o2 sensor situation...let's hope you have them first!
