Gearbox Code Question

[JBL930]

I have seen a gearbox that has stamped on it G50052 and i am trying to accertain whether it's a G50/05 or a G50/52, here is a pic of the stamped code



I've managed to find this info from a kit car forum, i'm sure it'll also be on here somewhere but couldn't find it, i can't work out which one it would be, any help would be great. Maybe someone who has a G50/52 could have a look at how the code is stamped on their gearbox? Thanks again

Jon, not much help but I think it's a G50/05. I think the 2 describes the differential as a LSD. I think the ratios wil be too low for your awesome machine
