Sounds like you have mostly accurate info about it.  Keep in 
mind that unless the tranny you get actually came from a GN, 
then it won't be strong enough to deal with a 350 in a truck 
without some beefing.  Talk to a reputable local 
transmission guy to see what's involved.  Hopefully the 
tranny you're looking at is the dual bolt pattern type that 
will bolt onto a chevy.

The TV cable is critical, you can either use a kit or cobble 
something up, but it needs to be right, and adjusted 
properly (possibly using a pressure gage) for long tranny 
life and good shifting.

I had a couple 200-4Rs laying around for years and finally 
got rid of both of them recently...since I'm into big 
blocks, they won't do me much good.
