Hi Sal,
Not sure how you'll fill in the blanks. Can you find another VIN # on the radiator support? Imagine if you're in front of the car and you lean over and put your hands on the radiator support. Your right hand will be near it, towards the battery, on top of the support. IF I'M WRONG PLEASE CORRECT ME!!!! Any how, find another VIN if you can.
Here's a Year One page with VIN info. Maybe you can piece something together.

Maybe the second digit, the "I" is part of an "H".
23 is for 2 door coupe.
You don't have the engine code (5th digit) so look for the other locations for a VIN #
"0" = 1970 model year,
"B" = Dodge Main, Hamtramck, MI
and the rest is the sequential production number starting with 100001
Check the pad on the passenger side of the engine block, just above the oil pan for #s. Looks like you have some sort of a small block being that the distributor is in the back. Would be interesting if the #s match the last #s on your VIN. IF it does, and that's a big if, then you will be able to find your 5th digit of your VIN #.
Does anyone know the all locations for the VIN #?
