Has anyone heard of a 68 1/2 production run?

Sorry 375instroke but the sequence number and shipping order numder are two different things.
On a 68 your full vin will be on the dash tag,
broadcastsheet,Certicard,title,original window sticker,and sometime in the back of the owners manual.Your fender tag will have your parcel vin and your shipping order numbers.
Your shipping order numbers are found on the fender tag,broadcastsheet,radiator support,and trunk lip.
On a 68 big block engine a parcel vin is also found on the rear of the block at top near the bellhousing area.On small block I don't think there are any vin numbers.Transmissions have no vin numbers.

On a 69 your full vin can be found dash tag,fender tag,broadcastsheet,Certicard,title,Original window sticker,and sometimes in the back of your owner manual.
Your shipping order number can be found on the fender tag and broadcastsheet.
On a 69 a fulll vin can be found on your engine and transmision.Your radiator support and trunk lip parcel vin 8 numbers if I remember right
!st number will be the year,2nd number will be the plant the car was built at,and the last six will be the sequence numbers.

Hope this helps,Jim
