Allen Socket Locking Set Screw for Porsche 911, 912, 914 and 914-6

Working on that pesky shift linkage? Don't forget the most important part; a new locking conical set screw.  Don't risk that old set screw backing out.  See that plastic locking plug?  Your old one is all worn, dry and heat soaked.  Do it right.  Do it once with a new screw or two.
