where is the oil dipstick in a 1972 t-bird 429?

If memory is correct, it may be on engine front passenger side, between water pump and alternator. If you still can't locate it, try looking underneath, at oil sump pan. The tube will exit on left or right side and angle up. I think the drain plug was on the same side. I hope your oil dipstick was not misplaced last time checked!
