Hello,
i've fitted in my Defender 200tdi a short bellhousing R380 TRC103140, less than one year ago.
I'm now in a middle of a new project to fit a TD5 engine with the R380 from that engine, which obviously as a different bellhousing...so mine is for sale. If interested please send me an email to paulo@all4x4.eu. I'm in Portugal but I can give you some references to whom you can speak in the UK.
Cheers.
