Do you have any measuring tools? Otherwise, from just the the pictures, there's an off-set built in, so that rules out an LS or 4.6/ 5.4. So more info possible?

laying them side by side with a 340 rod and measuring it they look to be identical, but I’m not an expert either , can’t find any other markings on them
