I need help. I'm putting a 4BT in my 36 Ford truck on a mid 70's 3/4 ton Chevy 4 wheel drive chassis. I thought I had the answer with 5.9 vaccuum pump but I can't find an oil outlet on the driver's side of my motor. Any suggestions? There's a little freeze plug insert just above the pan, but it's not threaded--looks like it goes into the pan. There are two small (Take 11mm wrench) plugs along the block, but they look like they go into water jacket--and above there's a 3/8" or so plug up by the air intake box for the turbo. In short, I'm not finding a pressurized oil outlet--a guy I know says some blocks had them on the driver's side and some didn't? What to do? I could go with an electric vaccuum pump, but like the idea of mechanical better. Appreciate anyone's experience, ideas, help. Thanks, Dan Smith, Tabor, SD
