Thermostat housing is on now just to find the upper and lower hoses

I have searched a few times - seems most suggest the Upper hose to be a Gates 21439 but that has the water neck that comes up and out at like a 40 degree angle, my LS3 has it coming out totally different.

I also couldn't find a clear answer on if the lower hose Gates 21439 had the correct end sizes ?

Neither of the autoparts stores had them in stock or I would have tried
