I just wanted to let everybody know that I think I found a 90 degree fitting for the c4 transmission cooler line. I have not been able to find one at a hardware store around me but I think I found one at Cj pony parts.com. Here it is…https://www.cjponyparts.com/cooler-line-fitting-90-degree-c4-transmission/p/HW1403/.
I hope this helps somebody.
You can buy them at a NAPA store. Eaton Weatherhead makes them.
