12 bolt chevelle

[68chevelles]

Just purchased a 12 bolt chevelle frame and rearend. Asking for some help.The date code on the center section appears to be h-22-6 or 8..Cant make it out. CW is stamped on the pass tube. Would this date be for the next model yr.. like 67 or 69? thanx

Late August build would be the following model year.In this case 1967 or 1969 models.
That CW was used from 1964-69 Chevelles with 3:31 non posi rear.
Look for a CON VIN Stamped on ther Frame.Check Drivers side over the rear tire,or passenger side rear horizontal rail.

The numbers i found were on the left rear on the horizontal part of the fram right behind the rear tire.
3943331 S 190 and 8 6 9 1 XK directly below the first series of numbers

Should the vin of the original body be stamped somewhere? I have no idea where the body is,, all i have is the frame in pretty bad shape. According to the measurement between the backing plates this is for a 66 or 67..

[Mr70]

Yes,sometimes the Body's VIN# will be stamped on the frame,but not always.It will be a shortened VIN#,called a CON (Confidential) VIN.
Example-if Cars full VIN# is 136379K123456,look for 19K123456 stamped on the frame rails were I described earlier.
The other numbers you stated are the Frame Part number etc.
Breaks down as:
*#3943331=is a 1969 Chevelle 2 dr. frame.
*S= is A.O Smith Manufacturer
*8=August
*6=day
*9=year
1-Shift
XK=was used as a 1969 Chevelle Frame suffix code.

So is it safe to say this was prob. a big block car or could it have been a small block? being a 331 non posi
