But since the 3.07 and 4.11 are optional would they have been listed on the vin? I'm not a vin expert but I was thinking when you went beyond what was standard all options were then listed on the vin?

EDIT: Forgot to thank you for the Heritage Center link for Burbs ... Thanks!
I've already printed it out.


I think you mean the SPID, not the VIN. I would think any optional rear axle would be listed on the SPID.

There may be a code stamped on the passenger side axle tube. (see pictures) use the first two or three letters of the code (depending on how many there are) and look it up in the charts here.....

The code in the pictures below would be TDE


As far as the cross member question are you talking transmission cross member or front engine mount cross member? The front cross members are the same but the 250 I-6 and V8 engine frame brackets are different. Also the 250 I-6 mounts in the rear holes on the top of the frame rail and the V8 mounts in the front holes. The 292 I-6 is a completely different animal as far as mounts......
