well the axle casting date is november 22, 1968. The date on your fisher body tag, 11D, is the 4th week in november. That puts them close and the axle is before the body. Id say as long as your vin ends in around 20000 the numbers side of things looks good. but i looked back through the model ID pages and the only 327 listed says export on it. Was the 327 not offered in 69?
