M50 swap steps from completion... a few quick Q's

[noog]

Hi Guys,

I forgot trottle cable and oxygen sensor from the e34 I had as doner. I understand I need the sensor for any near decent fuel economy is this a wire straight into the ecu plug???? e34 cable or ????

Do any of you have that available I'm or I'll hunt on ebay?

Any help appreciated...

Also

My cabbie fromerly a 320i will be for more relaxed driving style so I'm looking for a low diff 2.7ish or 2.9??

considering the diff case size will I need drive shafts etc or can a low e30 diff do the job with shafts I have.

A mate has parts from an e12 2.8 auto which I'm also gonna check out as to ratio etc. Would this be far too low...

cheers Guys

throttle cable is £12 odd new from the dealer so not worth looking for a second hand one imo not sure on the diff front when i do this im using an IS gearbox so i can use my E30 LSD
