need new swivel housing but which one? HELP

hey guys i need to get a new swivel housing as my mecanic told me, he told me to get the parts myself but i dont know what one to get, i have a 300tdi disco 1 m reg, the last bit of my chassis number is mal23080, so can someone point me in the right direction please, as i need to order it tonight to get it fixed ready for wales at the weekend

thanks

I'm sure the nice people at Paddocks will be happy to help with the information supplied. (Other land Rover parts dealers are available)

I got the same age one, Paddocks Teflon coated was the ones I fitted, been good so far, no signs of wear etc and not a drip of oil

Course, they might be empty
