Matt: Good news on 5th! The pictures are a bit fuzzy, you will have a very hard decision to make regarding the 5/R slider. I cant really see the 5 synchro, do you have a metric v. caliper that you can measure it with? I have a hunch, by the shine, that it is bad, which means, to guarantee good shifting, if you replace the 5 synchro you should also replace the 5 slider. Need a better picture of those slider teeth!

I should add that, if the inner teeth on your 5/R slider are crisp & sharp (no roll-over or spread on the tooth tips), if there is one place you can risk mating a used slider with a new synchro is 5th. All 5th gear shifting activity takes place over 50-60 mph, so you have that working in your favor. The used slider will still shave off some friction material on the new synchro ring, but that is not nearly as critical as putting a new synchro with a used slider on 1/2.
