Frame VIN
I searched and the best I could come up with is the frame VIN is stamped on the top driver's side. Can anyone elaborate? I can't find it on my 1978 F150 4x4. Is it by the front crossmember? Back by the firewall? Thanks.

on the 4wd it SHOULD (but isn't always I guess) be between the front cab/body mount bracket & coil bucket on top of the pass. side frame rail. You might need to wire brush a bit to get to it. And some were stamped pretty light & barely show up.

He's not the only one. I've been called a liar a few times, but my frame isn't stamped either. I had the body completely off the frame and wire wheeled the entire frame and searched with a bright light for 3 days. My frame isn't stamped.

Found mine last night on the top of the frame between the radiator support mount and the front cross member on the pass side.

My driver door came off a '77 so I wanted to make sure the cab VIN matched the frame VIN before I order a Marti report with replacement door tag.

I've tried to look using a mirror but couldn't see anything. I know my cab has been swapped cuz it's titled as a 73 2WD but it's on a 74 4WD frame & drivetrain... it has a Ranger bed based on its emblem holes... pretty much a Frankentruck but I am a happy dentside owner.

It was right where you said it was, thanks! I looked and looked but couldn't see anything. Then I could make out what appeared to be a J which is part of my cab VIN. So I sprayed some engine degreaser and waited, washed it and more became visible with some rubbing with a rag. Brake cleaner and the rag made the whole thing completely visible, and it's stamped very well.
My driver door came off a '77 so I wanted to make sure the cab VIN matched the frame VIN before I order a Marti report with replacement door tag.

With all the dust/dirt that settles on top of the frame since there's room under the cab they take a bit of cleaning to see. Just like the ones up front, so it's no surprise, but I wonder if ones there? Maybe the previous owner ground/sanded the front one off due to the cab swap? California does base VIN of vehicle on the frame VIN - not cab, so if it was a cab swap maybe they wanted to run the cab VIN and made the other disappear.
