i replaced/modified mine last week on my two wheel drive the rubber completely perished i couldn't find a new one anywhere as they come as a complete unit [from bottom of steering colum to rack] so i bought a new standard sierra rubber steering coupling from ebay for £8 the rubber is exactly the same as the cossie one so just change it over, you have to cut the two rivets of your one and nut and bolt the new one on[use high tensile bolts and locktight] works fine
