GASKETS
by Terry from Luthersville, Georgia on May 03, 2014
YOU NEED TO UPDATE YOUR WEB SITE. I ORDER HEAD AND INTAKE MANFOLD GASKETS AND THEY ARE THE WRONG PARTS. YOUR LISTING ARE WRONG. FOR EXAMPLE THE PART # FOR HEAD GASKET AND THE EXAMPLE IS THE SAME, HOWEVER, YOU SENT ME HEAD GASKET THAT IS FOR BIGGER ENGINE. THE INTAKE MANFOLD LIST FOR A 6 CYL AND 8 CYL AND I RECEIVED IT FOR 4 CYL. I ORDER THE SAME PARTS FROM BOAT BANDIT AND RECEIVED THE RIGHT PARTS. I WILL DEAL WITH BOAT BANDIT. THANKS VERY DISATFIED COUTOMER
