Oil filter for 351W CR's is PH43. Also cross references to SB Mopars so it's a decent sized filter for the 351 sized engine. Found it in a cross reference. Standard Ford PH8 will NOT fit the 351, and only barely fits the 302 in stock location. Too long. PH 16 used in 302 powered MII's will fit and work, but kinda short. PH (or XG) 43 seems to get the job done.
There is no interference between the lower rad hose, and steering linkage. Granted, everything is a tight fit on the drivers side of the engine, and has to be mocked up first to check everything, but it all fits...just. (Add power steering, and things get tighter still).
