Are gt shifter cables the same as the st205 shiffter cables? Options

[02bluerolla]

Hey Am trying to get my lsd tranny to work but I keep having problems with the shiffter cables, I bouth some shiffter cables from the UK which the guy said their from a GT4 st205. I looked at them and they look pretty identical in length to the regular gt cables. Are they the same? My mechanincs says the gt are not long enough and the st205 dont seem much bigger.....

and about the rear mount, is their an alternative to it, cause i cant find that one.
