I found mine today & it is a front sump, not sure if any of the several pickups I have is the right one for it. If it turns out you need the front sumper (& I dont) then I will mock em up & see if one of em is the correct one for that front sump pan (I'm drilled/tapped to 1/2 NPT so I wouldn't need/use an OE front sump pickup IF I have one). 65 D100 451
