I wouldn't change out the synchros, because there's alot of people that a spend thousands of dollars on their engine upgrades but no one is willing to spend anything to come-up with a alternative for this!! or at lease experiment!!
*The problem with the syncros: too many teeth to engage together with the gear.
*Solution: redesign new hub/slider/syncro with less teeth that are evenly spaced out apart
-back to you!, If you have a alternative to travel-don't buy!
(Then: aftermarket peps will have to experiment or create something!!)
