horray - it's in...I think for good this time. Ultimately went with a pair of nice simple p-side motor mounts from a 94-98 Grand Cherokee (same # for each side), which gave me plenty of room for center dump manifolds 👍 . BTW, the Wix 51515 is the 'longer' oil filer, which according to my research and talking with Wix is the same filter spec for the magnum...just longer, and hence 'more better filterage'...
