Swivel help

My Series has Disco 1990 axles with Series diffs. I am trying to replace the swivel & cannot identify the correct swivel ball. Mine has a machined seat for the bush on the half shaft to sit against. I know it is not the FRC7065 ball as that does not have the machined bit. Everything is 10spline & it also uses the 8mm seals.
So is the axle a 1990 Disco
The number on the axle casing is 34LO3188C I think but it is difficult to read so may not be 100% right.
I have a copy of Rave but it has 1995 on for the Disco & shows a setup with the drive flange seperate but I have found a doc on line that showed an 87 Range Rover with a similar setup but there was a spacer on the half shaft
Old swivel on the right

Half shaft showing bush

Housing showing outer bush the CV runs against

My drive flange has the end shaft attached not with nut & shim etc

The CV is "floating" if thats the right term - it is not an interferance fit the shafts just slide out
Can any one held identify the swivel ball I need
Does anyone have a manual that shows this setup - if I know the vehicle I can then perhaps find the right part
I need to get this sorted so any help gratefully received

it is frc7065 ,there is only 2 used frc7065 non abs or ftc5105 (frc2644) which is def pre 300 tdi ,where did you buy swivel obviously not finished to fit earlier disco

Came from Paddocks - but online supplier also confirmed FRC7065 does not have the machined bit

they did do ,ther has only been 2 swivels made for def and disco and rrc after early 6 bolt fastening on rrc that is frc7065 for all non abs rrc and discos and def 300tdi frc2644 (ftc5105 teflon coated frc2644) for pre 300tdi defenders and asbs rrc disco
