MK6 Rear Leaf Spring

[103keef]

Looking for just 1 spring for MOT.
2.4 RWD semi high Van. 90 T350 registered 2002 but think it was built 2001 or maybe earlier!
All online searches suggest it has a 2+1 (3 leaf) arrangement but it is definitely only a 2 leaf at 60mm wide.
Not sure if perhaps the whole rear axle and springs could have been swapped at some point.
Rather than trying to put back as it should be, I would rather just replace the one needed spring.
Van doesn't carry any weight so not concerned about loosing a leaf!
