PM me so I won't forget. On H-T, one of the web-banners sells just the rings itself.

But, if the gear is worn due to the synchro ring was worn first, it is highly recommand to replace the set. Also, follow exaxtly what the helms states. Measure the linkage system inside the tranny. I've recently found out that if its out of spec, it will lead to synchro wear faster. Alot of guys missed this.

Also, another tip, inspect the shift linkage very closely. If the welds seems to be cracking, replace it. Shift linkage is key factor to the whole tranny setup. I had a ITR setup with 50k miles on it, well, after a shifting fast, the linkage started to bent thus making the tranny shift faster than the tranny could.
