The 89 thou # is in a few online ads including this one on Hemmings...

Best always consider Matching #'s as exactly that also having nothing to do w/ original engines unless specified.
Whether original L79 & paperwork or not, w/o more offered to suggest otherwise, most likely a stamper engine/trans?
Tough color but tone changes indicate individual panel paintwork w/ contrast too apparent for the # they're asking?
