Lots of questions after seeing those pics I'll post them In the mornin it's a pita on the phone.

[TRY MEH]

hoping i can identify this thing to be very sure what it is
but i tried looking for stamping its near impossible unless i can get a camera that can see in tight areas and bends, hopefully i can come across one that i can barrow but i doubt i can ;(

This is where larry is talking about....


Also, the LS blocks have info stamped in them in these 2 locations as larry mentioned.
