Ballbags

Right amongst mant things today I cracked on with driveshaft gators, no problem, then went on to taking the strut out. Nearly fooked up cos I turned the thread instead of the nut and nearly popped me spring off in sito..oops
Anway got strut out but knowing the stuff I usually buy from gsf is wrong I thought id check the size and low and behold my new strut top was about half inch taller than the one on the car. Have I been sold a non gti mount or do I have a 16v one fitted? Any help appreiciated chaps/chappeses.
