s4c tranny help.

[zdcarver12]

i was wondering if any other b series tranny synchros,sleeves,or springs would interchange on a hydro b16 s4c?i am really needing a 3rd gear synchro,sleeve,and spring.i don't want to buy a new one because i'm not sure it's my problem and i'd hate to spend the money for a complete synchro set or even 3rd gear.trying my best to find a decent used one just to see if that's my problem or i have more problems.i've changed everything possible but it still kicks out of gear,everyone i know in my town and surrounding area says synchro,except one guy said it's worse.the gears look fine,so i don't know what to do?sooo my questions is my buddy has a few ls trannys,not sure if hydro or cable,but i was wondering if i could take the synchro,sleeve,and spring off the ls and put on my b16 3rd gear.i'm guessing if that would interchange,the cable would be out of the queston.

if anyone knows or possibly has a solution,let me know ASAP!
