68 Roadrunner body and engine numbers location help needed

[Hotrod20]

Going to look at a 68 runner 10 hours away. Owner not very helpful in his communications.
The owner claims matching numbers. I can decode a 69 b body, but 68 is different.
Are the numbers on the radiator support and trunk lip like 69's?
The engine numbers are located on the rear of the block at the sending unit? and on the trans bellhousing?
Asking for help on identifying the factory body and engine numbers for authenticity.
Any help would be appreciated.
Thank you

I have 2 Lynch Rd. cars, and the rad support for another. None of them have the SO# on the rad support. I also have a St. Louis car, that does have the SO on the rad support.

My 68 has the #s on the trunk gutter and radiator support.

my lynch rd 68 has # on rad support and trunk gutter...... #s will match # on fender tag...... partial vin on trans and engine on top where they meet, but not all 68s have the partial vin

strange....... I have yet to see any unstamped core supports, unless they have been replaced......not sure what year they started, I pretty much deal with 67-up

On the St. Louis car, it’s on the engine side of the rad support like my ‘70 Charger. I can’t see it anywhere on the 2 Lynch Rd. cars, or this rad support from another.

All 4 cars are Satellites.

hmmmmmmmm........

When I get home I’ll remove that antifreeze decal and look under it. I thought I did that on the wagon though.

St. Louis cars seem to be on the engine side of the rad support. And Lynch Rd. cars are on the top in most cases.

What assembly plant? A= Lynch Rd. G= St. Louis. E= Los Angeles. B= Dodge Main.

Your comment "owner not helpful in communications" has my suspicious eyebrows raised. In what manner, avoidance, uncertainty, or ignorance ? I wouldn't travel 20 hours unless I was fairly sure what I was going to see.

Not sure

 

[440 PHIXX]

Yeah. My ‘68 G, St. Louis has the SO on the rad support as well.

 

[440 PHIXX]

Not sure

7th digit in your VIN.

 

[Charles Cook]

Can you tell by the fender tag?

That looks like a St. Louis tag to me. But your VIN if you have the 383 should be RM21H8? The 7th digit will be “G” if it’s St. Louis.

The last 6 numbers on the bottom line are the SO, and will be on the rad support.

This is the best picture I have until I get home.

Got it.

Looks like an “A” from here. That would be Lynch Rd. If you have the SO on your rad support, let me know the location so I can check mine.

 

[Charles Cook]

I will look in a few. I just so happen to be at the house having new springs put on the garage door.

I see you have a higher production #. It would be interesting if your car has the SO on the rad support. I know during ‘68, quite a few production changes occurred. The vent pulls changed early from the round ‘67 style to the square “vent” labeled type. The 0-150 speedometer in the GTX changed to 0-15, x10. And the ashtray changed from a slider to a hinged version. Those changes were in around late ‘67. Strange thing about the body numbers in ‘68… since they used the SO, they only appeared on the fender tag, broadcast sheet, and monroney sticker. Most people scraped off the window sticker. And the broadcast sheet wasn’t an item delivered with every car. So that leaves the fender tag, that got “lost” in a lot of instances.
