Milodon Oil pan fitment

Me too;30940 on a 70 DusterK, and a slight notch. I never gave it a second thought. I just grabbed the torch and Zip it was clearanced. The next time the engine came out I dressed it up.
I originally installed that pan for different reason. I ran it with just 5 qts in it on the hiway,and I was running a little 223* cam. My thought was that I could get better gas mileage with the crank not beating up the oil. I think it helped contribute to the 32MpgUS that combo made.
I had to make a belly pan for that pan tho, cuz I kept snagging it on stuff and got tired of brazing up the holes. Now I fly over everything, yahoooooooo!
