5th gear popout

[Matthew Bromberg]

Hello, I've had nothing but problems with my infiniti
G20 since I bought it from my friend two years ago.
I've replaced the engine and now I have to fix the 5th
gear popout.  I've found someone to help me rebuild
the transmission but I'm unsure of the details, parts,
and tools.  I found the parts list for the nissan 5th
gear popout at:
http://www.se-r- list.org/fifth.gear.phtml
I'm curious if this information is what I need to
rebuild a 1993.5 infiniti G20, and if so - do I need
to order the parts directly from infiniti or would
generic parts work as well, and what if any special
tools does the labor require.  I would really
appreciate any help, thank you
