oil pan drain bolt

No harm, no foul. We are just giving you a hard time. I think this is the first time we have seen small block in an end loader questions asked here. We need to think out of the box. Like: I don't know which pan is on that but you may be able to find a different application with a different sump to make your life easier. Just thinking outside the box because we have to.
Man. I don't know.

I'd have to drop the steer axle or lift the engine.

One requires welding an overhead hoist onto the frame so I can safely lift it.

Other idea requires lifting the entire machine, and welding. I'd have to weld up my own Jack stands too, in place, then torch them apart. I wouldn't be able to move them.

I'm out here in the dirt 400ft away from the shop. I made a really sketchy 240v to 120v adapter and have 20amps of 240v out here over standard 12ga ex cords.

so I have a light bulb and small dc inverter welder. Its impressive for 450ft of extension cords!!!

I'd rather blindly reach for that bolt., and assume its a 1/2 20 and be out a $20 drain valve.
