HELP! Looking for either part numbers or were i could get a new oil pan and pickup tube for my 1966 D100 with NP435 4 speed with the 225 slant six.

Assuming you need the rear sump pan. I was able to get the pick up tube from Rock Auto. Just type in your application. Had a very hard time with the pan, though. Got it from a 1980 D150 sitting in a field. You pretty much have to pull the engine to get the pan off. Best of luck.

Thanks Everyone

Yes they are front sump oil pans... doubt you will find a "new" one, but you might be able to find a used one here:
