Believe it or not I have been into my mopars since the late 70s and I have never really looked or cared about numbers matching issues as I have always known the history of all of my cars now as i am possibly going to sell a couple of them how does the vin actually show up in the engine # and manual trans, and rear end, on 68 high performance plymouth's? thanks

First off there is NO VIN on the rear axle assembly on any mopar of that era .

68 is stamped on the bellhousing flange near the oil pressure sensor and in the same spot on an automatic or on the id pad on the side of the trans on a 4 speed . It will be the last 8 of the VIN , and will NOT match the number stamped on the body . the only way to tie the body number to the VIN is with the FACTORY BROADCAST sheet .

No VIN or Sequence numbers on Dana 60 axle housings, but the assembly numbers and date codes stamped into them would have aligned with the cars Scheduled Production Date so it's always nice to check and confirm them. After the basic VIN/SO numbers have been found to match, dated coded parts are the "next level" when it comes to checking originallity IMO

where on a hemi 4 spd road runner? should the engine block # have the vin #s in it?

Matt, Hemi's would have the number stamped in the location that John pointed out.

Scott thanks, should the last 8 digits of the vin show up on the engine block also? I think I have the part # I dont think I have the right # the number I am looking at is 4262447004

Post a pic of your number and I'll try to figure out what you are looking at. Here's a guess before seeing a pic.

4262447004 = 426 Cubic inches 2447 April 09, 1968 004 4th engine assembled on shift


That looks like the assembly number that would be found on the bottom oil pan rail of the engine?

Here's what a trans stamping looks like (passenger side raised pad)

thats exactly where i found that number Scott, i will look at the top area up near the oil pressure sending unit? The area near the flange that attaches to the bell housing ?

Yes, exactly

Matt did you miss the picture Scott posted above ?

the number I found on the trans is 63292 does that make any sense? Thank you Scott as always you are very helpful!!

I saw the picture John, I am going down to the garage to find all of the numbers. Like i said I never really cared about the number stuff as I have had all of my cars for years, Im kind of embarrassed! And I just and out of the 14 cars I have 12 broadcast sheets that i have just found and some extras that i will post soon. Of course my hemi car is one of the broadcast sheets I dont have?

I found the trans # PP8333603 and the engine block number that I could read was 2812 was all i could make out which does match up with the Vin!!!! yeah!!!! and the rear end is 4 24 8 B 1 and there was another # on the trans which was it looked like
OB 168292 ????

You should post a pic of the trans numbers, that looks like a later model trans if I am deciphering it correctly. The rear end dates seem to align with the engines assembly date, those tow are likely original to the car.
