So not sure if I'm in the right spot. If not I do apologise

Recently bought a 2004 Mitsubishi lancer ralliart 5 speed manual. 2nd gear synchronizer went out and I'm having a hell of a time finding the parts to rebuild. I was wondering if someone could help me find it or a replacement tranny. I've heard the tranny from the evo x would fit. 2nd gear is now completely gone. Won't stay in gear at all. 1st and 3rd are starting to go. I'm also going to replace the clutch as well seeing as I feel this is the reason why the syncros went out. I have been searching for well over 2 months to no avail please help before I have to scrap this 💎 in the rough
