THE FLYWHEEL COVER USE THE 3 BOLTS PICTURED BELOW TO INSTALL THIS COVER. THIS COVER GETS NO GASKET OR SEALER - THIS ALLOWS IT TO DRY OUT ANY CONDENSATION OR EVEN IF YOU GET INTO SOME WATER THE 3 SCREWS ARE DIFFERENT LENGTHS BUT IF YOU PUT THEM IN THE COVER BEFORE INSTALLING THE COVER YOU CAN MAKE SURE THE SAME AMOUNT OF THREADS ARE SHOWING THROUGH ON EACH, SO YOU KNOW WHERE EACH GOES NOW BECAUSE THIS COVER COMES BACK OFF WHEN INSTALLING THE ENGINE I WOULD JUST SNUG UP THE BOLTS AT THIS TIME @ FLYWHEEL SCREW KIT 6X28 6X35 6X35 1/21P (HEX/BOLT/6X28/6X35/6X35) HEX/BOLT/6X28/6X35/6X35
