I think the frames are similar to the 63 and 64 galaxies and you might want to find a set of 289 motor mounts for a 63/4 galaxie and see if you can bolt in a 302 in your 59,if you cant find any a local rod shop sells mount kits for you application. After you get the motor in it should only require a little tweaking to hook everything up and if yours has a manual trans you will have to find a mid 60s and up trans as the early 60s on back have a different bolt pattern where it bolts to the bellhousing. If you dont want to wire in a altenator all you will need to find is a 63/4 generator brakets from a galaxie with a 289 and your generator will bolt up.
