Thread: SR20DE and SR18DE axles the same?

Hello from the Philippines! I have a U13 Altima with AT tranny and SR20DE as stock. I will make it a manual transmission next month. What I have now is a manual transmission (gear box, flywheel, stick, clutch and brake pedals, linkage except the axles) from a U13 Altima with an SR18DE engine. My question is, will my current axles (SR20DE AT) fit to the SR18 gear box? I searched the web for answers but I haven't found any similar topic. Any input will be appreciated. Thank you!
