I get to put my car on lift soon. where do I find ALL numbers to verify it as all original. I think it is but want to make sure. carb,vin,frame etc.... Yhak you, Eddie

 

I got most of that info on this site's WIKI...carb,intakes.block,heads,trans.....O.K. some from Joe P., Derek

 

This will all depend on what *exactly* what you mean. By "original", that literally means what actually came on your car from the factory.
Being a '69, there will be a VIN derivative stamped on the block and the transmission. Those are the only things that can truly be thus verified as being original. Other components can be checked to see if they are "correct", but can not be proven to be original. Same basically with date codes.
This is the reality of what the vague term "numbers matching" means for Oldsmobiles.
