Well my axle is a GM t170 so the back cover is solid which threw me off but I looked them up and they are made like that so it wasn't some crazy hillbilly with a welder haha... but if I were to do that I'd have to take the whole (center)gear section out the front. What's the correct term for that section? But I'm not really wanting to do that but if when I drain it and there is some chunks and/or metal shaving in the gear lube maybe I'll take it off and check things out.
And yeah the high/low selector has the eaton logo stamped in it so maybe that selector isn't original, idk much about the two speed rears other then splitting gears, and fortunately for me it will also give me a 5-8mph top speed gain according to the calculator on the spicer website. And this axle has the dayton style rims which are tire shop serviceable so that saves me a lot on rims/ tires cuz these tires also have decent tread on them.
