You are probably gonna need a rebuild. Sounds like you cracked a synchronizer ring or just ground the synchros to pieces. Could also be a bent shift fork. There is no way around it, you will have to ge *** fixed. Having been there it is cheaper to just buy a rebuilt for about $1500 then deal with buying the few parts you need and the $700 or so for a rebuild. A synchro alone can run you between $180 -$300 depending on the year and which one it is.
