Powerglide Coolant lines

[chtr65]

I need help figuring out the factory correct parts for the powerglide coolant lines to radiator installation. I purchased coolant lines from a parts supplier, the lines end with a 90 degree towards the ceiling. The supplier tells me that there is supposed to be a 90 degree elbo fitting installed into the radiator first, then the lines get connected to those. from what I can tell, It appears the they should have a slight bend just before the ends. So they go staight into the radiator tank without the 90 degree elbows. I sure could use some help with this. Thanks in advance. Mike
