Slant 6 engine decoding

I think more of the info you need is in this thread: No Vin Stamp? - post #18

In that case, the number worked out like this:

PT: Assembly Plant
225: Engine Size
R: Regular Fuel
2482: Assembly date on the Mopar 10,000 day calendar (Day 2482 is Tuesday, May 14, 1968 )
047: 47th assembled that day.​

So, that would indicate that for your car - the first 3 are the same,
the assembly date would be (from https://maxwedge.com/articles/10k.php) Day 2454 is Tuesday, April 16, 1968
And the next 3 would be 094 - 94th car?

The 9 afterwards is puzzling, though...it's also down lower, like it was stamped later? (but the 0 is a little high, too?)

HTH!
