I have been thinking through this same issue with fuel filter. I have been considering using the Ford oil filter racing adapter. It redirects the filter 90 degrees, so I think you could aim the oil filter back under the compressor.
Thank you for paving the way for my build
Did you convert the front axle to 6 stud?
Is there any interference between the steering box [looks to be 60 series?] and the panhard rod?
Lastly, do you think there would be any issue with flipping the panhard rod left to right and installing it 'backwards' for a RHD rig?
