Post fifth gear synchro

Has anyone replaced their fifth gear synchro? My car started grinding in fifth after a good dirt road beating . Unfortunately I do not have a warrantee ...
Is It a pain? Is there anything I should look out for? Any info would be great.

<FONT face="Comic Sans MS">Is it expensive for the parts? Not really. However, you have to drop the transmission (ie: remove it from the engine, pull the front 2 and the rear driveshafts, split the case, pull apart the main shaft, and there you go. I just had my 5th gear and 5th gear synchros replaced (under warranty thankfully).

So they commonly replace the gear along with the synchro? That sucks, I just bought the synchro for 14 bucks but I haven't bought the manual. I dont want to if I can get enough info and do the job without it. I have been inside the gearbox on my rally car so Im not new to cracking a case.
I just hate supprises....

<FONT face="Comic Sans MS">No huge suprises I'm aware of, but you might need the main shaft nut and washer too, as they are stamped over the main shaft to keep it from backing off under use (that was actually what happened to my tranny... the nut loosened, backed off, and the movement/wear broke number 5).

You have to pull the trans and remove the rear extension housing.5th gear is on the outside of the rear part of the trans.No need to split the case.The nut has to be removed that is staked,a roll pin,and then you slide 5th gear off.Then you just reverse the order to install.
