update- SOLVED!!!! alright so the rusty splines were not the problem. I lubed them up and nothing happened, so i said eff it and I bought a new clutch. so I just pulled it off, and sure enough one rivet of the friction plate part of the clutch popped off the spring. I haven't actually verified my trans shifts better but I see no reason why installing this new clutch wouldn't fix it(if it doesn't fix it my mind will be BLOWN). lesson learned here is be thorough with inspection, because this whole headache could have been avoided if I actually took my time instead if rushing through things. leaving a pic of the clutch as well.THANK YOU ALL FOR THE RESPONSES!!!!!
