Luke,it is true,low beam T-3's are not as common as high beams, simply because no one drives around with highbeams on all the time (except when they are on the same road as me) Be aware that there are 2 "types" of T-3's. Aftermarket T-3's are available for the years 67 and earlier. They don't make them yet for 68 and newer. You can do what I did, place an ad in the "parts wanted" section. You will be amazed at the amount of replies that you get. As for price, you will see a wide range of prices. Deal with someone you feel comfortable with and you can get a good set for a reasonable price. Good Luck !
One note- "early" and "late" T-3's ALL function in your 69. Unless you are going for points in shows, just get a matching set, remember that they aren't the brightest lights out there...
