If the strut top plate does not have the original factory spot welds holding it to the body then the number doesnt mean much.
Alloy id plate is right for twincam (CK49) and matches strut top plate but these could both be from original tc wreck.
A couple of other things I noticed,
no remote master cyl reservior bracket. Why would someone chop this off?
Slam panel has no cutout for heavy duty radiator. The shroud that is there was originaly cutout on the production line very roughly with an oxy torch and an infil screwed over the top.
It might still turn out to be an original although fairly altered shell. Let the buyer beware.
