Tim,
I replaced my front ones with an LED pair from a newer MG model that I found on the AF1 website. With a little modifying they fit the existing stalks. For the rear I used some small ones from Morimoto. The front ones didn’t require resistors. The morimoto came with resistors built in. Both required cutting and splicing. I can send pictures if your interested but you can probably find some of this by doing a search like Paul mentioned. Good luck.
