Welcome to the forum.
The hazard flasher in your car is the rectangular one behind the drop panel, it was originally a Signal Stat 180. however it can be replaced with a round equivalent.
The turn signal flasher is located above your left knee ( assuming a left hand drive car). remove the cardboard curved panel under the dash.
It was originally a Lucas FL5.
now then… IF you are wishing to install LED turn signals you need to search for a long thread on LED FLASHERS . LED Flasher comparison
AND, I would check the hazard switch for bad contacts inside the switch. Thats a whole 'nother can of worms, but odds are its not the flasher thats your problem.
