ok i bought a set of bucket seats for my 73 barracuda with new covers on them,they were shiped with the top of seat taken off from the bottoms,,my question is are they that hard to put back together or did i get tops not matching the bottoms,,never messed with seats before but i cant get the hinges to go on the studs sticking out on the bottom seats,,,are there some trick that i dont know or did i get burned,,
