cylinder position

[Knarley1]

I own an LMM and I recently got a check engine light which is P0675 #5 glow plug. I bought a glow plug but I don't know which side #5 is on. I looked at another forum and is said drivers side was 2468 from radiator to firewall and passenger side is 1357. I just want confirmation before I replace the glow plug.

Your info is correct. #5 is 3rd from the front, on the passenger (right) side.

Just a note: All GM V- engines are cylinder-numbered the same way, in that, the forward-most cylinder is #1. Or, from underneath, by the connecting rod position on the crank.
