front half shaft Universaljoint

Hi all sorry to pester again. The front swivel bearing had collapsed on the series 3 landy due to no oil in there for a long time. the half shaft UJ was also very loose so I ordered a new one part number RTC3346 but its too big, the cross is larger and the bearings are deeper does anyone know the one I require? Its a 1981 series 3 petrol.

Thanks Mick
