uh, where'd I put that pic at ... uhh, oh here it is!

The spring has two "legs" that go around the rod there on the right. If you pop the legs off from around the rod (I hope this makes sense), but leave the spring part where it is, it might make a difference. The spring will be able to "spin" around on the rod that goes through it.
More advice: Have someone who can drive stick take a quick spin and see if they have the same problem (if the spring doesn't fix it). The synchros are prone to crapping out and grinding going into gear is a symptom. Hope it isn't, because that's a tranny rebuild and big $$$. I've had it done twice (once on my dime).
