I feel your pain. I'm 6ft 1in tall and need a similar sleeve length. I've had a moderate amount of success looking for tops, sweaters, and jackets which have 'thumbhole' sleeves. These have a cutout in the cuffs so you can put a thumb through them. I rarely use the thumbholes, but tops with this feature usually have extended length sleeves. Other than that, get used to 'long sleeves' actually being 3/4 length. Good luck!
