I am trying to figure out the O.D. of the stock plastic housing for the oil filter. I am considering getting a set of rare earth magnets to run on the exterior of the plastic housing while I'm awaiting the Jowett performance restock, but need the data first. I know I could remove the skid and check myself, but I have spent a lot of yesterday rotating the tires, getting beat on by the spare tire winch mechanism and lubing/covering the KDSS screws (5k miles and surface rust already???). Does anyone have access to the specs of this housing? TIA!
