Oil Filter Change

Hi Guys,

Getting to that point of changing the oil on my '72 Demon with BB. Few questions for you:

1. How often do you change the oil if only driving ~5000/year?
2. How do you access the oil filter to change it out? Almost seems like I have to remove the front sway bar just to get to the filter and hope that I can pull it between the block and radiator.

Anyone have insights?
