Just adding a bypass filter is pretty straight forward, you either use the stock style canister type filter which clamps onto the intake manifold (which is perfectly fine to use and the easiest option), or cobble together a spin on after market filter with the appropriate small size hoses (or use fittings that you can solder closed and drill the appropriate restriction), also a perfectly fine solution.
The reason that is so important to use the proper size lines or restriction is that with a bypass system, the oil filtration system is designed to tap off one of the main oil galleys, then bleeds a little pressure off the main, filters it (using very small inner diameter hoses so no large particles will filter out anyhow), and then dumps the clean oil directly into the pan where the now clean oil is instantly diluted with dirty oil. Lines with too large inner diameter bleed too much pressure from the main and you run the risk, especially with an older more worn motor (read that oil pressure bleeding past the larger bearing clearances generally found in a worn motor), of starving the bearings of the oil and pressure needed for continued service, potentially leading to a bearing failure. Its not a particularly efficient system but it does provide some, albeit, limited, measure of filtration. The thing is, if you are driving your truck every day and putting thousands of miles on each year, it may be helpful. But if you are like me, my motors don't go more then 1000 miles, usually less, before I change the oil. A regular oil rotation back in the day would be like every 3000 (except for the fussy) and a lot of the time longer then that. So regular oil changes in my view are more beneficial then adding a bypass filter.
But you are right, its a hard habit to get away from. I generally ran filters for years with my motors, but on this last 261 build, I decided to forgo a filter and it was strange in the beginning but in the end, no issues whatsoever and I am not easy on my motors.
