does your crawl box shift ok? i just put all my stuff together and the actual adapter wasnt machined all the way through where the shift fork slides. a few friends thought that i didnt put it together correctly and i knew i did. something didnt look right about the adapter and sure enough it wasnt machined out all the way. we just used a dremel and the shifter slides easy now. it just sucked to have to tear it all back apart.
