1st Gen Prius 12v Battery Replacement

[War_Wagon]

I am ordering up an Optima for my 2001 Prius, my question is do I need the D51 or the D51R? I am assuming they are the same, just with the terminals on the opposite sides, but I don't know which one to get. Thanks!

I have been told by a certain Previa driver that I need the D51R. My battery guy didn't have one in stock, but has a DS46B24R for a 2004 & newer Prius there. He figures if I can stretch the cables enough it will fit, and it has the proper terminal size on it. Best part is, I can take it back if it doesn't, so I will be the guinea pig and try it out lol
