The LH SL/R was released with 4.2 badges on the front fenders and bootlid. The SL/R badge replaced it on the LX SL/R. The LX SL/R also had a 4.2 badge on the bootlid.
^ How the LH SL/R came from factory.
Holden also put these badges on 4.2 SL's.
Apparently there were also 5.0 SL hatches; very rare; not sure if it had 5.0 on the fenders though.

my apologies for the fender remark, l had know idea they came out on Torana's, but I stand by the ones on the bonnet scoop. I'd only seen that badges on the HJ - HX Monaros. You learn something every day.
