Leaf spring bushings, again!

Hi all

Having great fun with my local Mitsi dealer, trying to get new leaf spring bushings. I think some of the trouble is because different people have different names for the bits of hardware that make up a leaf spring suspension.
The dealer supplied 10 rubber bushings and claimed that was a full kit of spring, shackle and chassis bushes. This seemed to tally with the line drawing in the Haynes book.
However, when I went to fit them, I discovered I hadn't enough of the correct bits to complete one side, let alone both.
On my Shogun the bushing at the front of the spring, where it meets the chassis, is a larger diameter than that at the rear where it meets what I call a shackle.
The dealer says it's not! His computer says both ends of the spring take the same bushings.
Now he's inclined to take the view that, being a Shogun and not a Pajero, it's an import and his records may be incorrect. Not that that gets me any further!
Does anyone know the correct part no. for the Leaf Spring/Chassis bushing on a 1989 LWB 2.5Td Shogun?
Have to show the finished job to the NCT man soon!
Fed-up!
