You will really like the 200R4 once you have it all together. I went with 3:90 gears but I should have gone with 4:10s. If you look here:
Will GM 200r4 work with factory floor shift location?
you will find everything I did to make the 200R4 work with the factory shifter. The biggest issue will be the 'trimming of the original upper cross member" which isn't that big a deal. I can manually shift through each gear if I choose to. I also modified the shifter detents to allow me to shift down into 1st gear, so I actually have first, second, third and overdrive. If you have any questions just ask. It was a bit tricky but it works really GREAT!! Hope you have a little patience and some imagination.
