Scion Xa to Yaris short shifter question

[Lightrfire]

Hi I have a question regarding the compatibility of xa short shifters in a 2007 Yaris. Most sellers will list them as compatible with both models but some won’t and I’m wondering if they are truly cross compatible or not. For example the ralco rz shifter for the Yaris is #914944 and states it’s compatible with xa and xb as well. However if you search for ralco rz shifter for scion xa it’s part # 914850 and also costs half the price. Meanwhile other branded ones list one part as compatible with all models. Are they cross compatible? Sorry if this has been discussed I did a forum search but didn’t find an answer.
