there are no stupid questions & your inquiry is a real good question. Yes it wouldn't hurt to confirm TDC & you can get SB timing covers with the marks on either side and or buy the bolt on pass side bolt on timing tab & I see em on FABO regularly or as said make a new pointer or tab & a white paint mark on the dampener (clean that area first with brake kleen) then roll on your tape then seal it to the dampener with spray clear lacquer so it will stay put & not fly off.
