[Baron Von Zeppelin]

Option 1 is dated too late - if you want correct dates.
In 1968 model year they used " I " as a month.
" K " is November .... sorry about that

In 1967 model year they did not use " I " .
That was the only model year that didn't use it.

If neither of those blocks has a VIN -
then your original would not have had one either -
more than likely.

Somewhere towards mid year - 68 model year - they started the VIN on block.

Do you have the PHS /BHC for your car ?
Does it show an ENGINE UNIT NUMBER ?

"think" the WS / HO came with 7028263 carburetor like the WT did .
