Part identification (oil pan)
That only fits one thing..........a 360LA, or nowadays, a 5.2/ 5.9 magnum with some sealer in the corners there on the front
The tube through the sump is for the steering center link
No idea what body it fits, it is not for a truck, tho.........
No idea who made it, it COULD even have been "shop made" by a skilled fabricator.
