Help to ID what this front brace fits ?

This has been in the back of a cupboard for a while and i have no idea what it fits, I had purchased it to fit my MK2 Golf at a show but when I got it home it just didn't fit at all

Dimensions are;

Height above level is 90mm
overall length is 1300mm
Adjusts up to 25mm each side
hole size for strut 115mm
pcd across the mounting hole centres is 150mm

If anyone can shed any light i'd be really glad.
