I have an Oct 1995 Volvo 945 which was dealer-fitted with a "7-seat" rear facing kit when I bought it. In helpfully changing a wheel, my teenage son has undone the wrong nuts in order to access the spare wheel, and much of the assembly is now lying apart - washers, nuts, collars, etc. Another problem is that one of the arms has locked into the straight position and will not collapse!

Does anyone have any information which might assist me?

Thanks

Adrian
