Schumacher KF with SV2 wishbones
 

OK, what is the reason for the Mod and any pics please?

If its the rear wishbone's , it because you have more wheelbase adjustment , and an extra inner shock mounting hole .

Yeah, I understand that part, trying to work out whether they are fitted right way round or opposite sides, what wheelbase you run etc?

It's for the wheelbase option, internal and outboard Can be adjusted. they are run the right way round on the kf. I have mediums fitted on medium wheelbase outboard and long inboard

you run them long (backwards) inner pins in the medium position, outer pin long in high grip, medium/short when the grip starts to go
