That's excellent!
LOL drag-200stang beat me to that punch line!
The part # 6306 is the Crankshaft's Timing chain Gear you all ready have that installed with the Timing Chain and Gear set.
The part # 6700 is on the Engines Front Timing cover or it should be already, its the Front Crankshaft seal its Lip Seal will be sealing on the Crankshaft Dampers Hub when its installed.
That only leaves The part # 6310 missing this is the Timing covers front Crankshaft Oil Seal Splash Shield /Oil Slinger Ford used these on all the early engines and then discontinued their use sometime on the later model engines. Since you are using a stock type timing chain instead of the Duel Roller Type you could use the Splash Shield if you had one otherwise if your engine didn't have it to start with it won't hurt anything if you can't find one to use. Good luck Edited
