My $0.02 ... (I am at work and bored!)

On my 86, I have deleted the cat and original narrow-band O2 sensor (hole plugged) and put my wide-band sensor just after the muffler. I couldn't fit it between turbo and muffler and this was only other option.
If it is at the right angle, it can be removed through a 25mm hole in the sheetmetal without dropping the engine.
I played safe and got a bit nervous about putting it before the turbo in the original location (where Rarly has it) due to talk of over-heating and possible turbo damage from a broken sensor. However, this is by far the easiest location for access.

I guess it also depends on whether you need to keep your original narrow-band sensor and cat in place.
