Having a right mare guys trying to remove the front passenger seat from my 2004 vectra c.. The adjuster mechanism is busted so i cant move the seat forward/ backwards so i wanted to remove the seat to sort it but no matter how many 13mm bolts i remove i cant get it to budge?? Cant see any thing else other than 2 large star keys at the rear of the seat // I ve removed everything i can see from the front but it wont lift yet?? Doin my nut in right now lol

Any tips would be most helpfull right now thanxs
