12 bolt chevelle
 

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

Re: 12 bolt chevelle
 

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..

Re: 12 bolt chevelle
 

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
