If you buy the t-5 replacement version of the Richmond then it is purely a bolt in replacement for the t-5, same bell housing, clutch, speedometer hookup, backup light hookup etc. It does ship with the needed cross member but it is kinda dinky angle iron (I purchased the Spohn richmond conversion cross member but it did not properly fit and required heavy modification). The new shifter and linkage ships with the transmission as well.
If you have a newer camaro with an electronic speedometer then getting a signal interface from:

will make calibrating your speedometer after the conversion easier.
The output of the richmond transmission does not match the stock yoke on the camaro drive shaft, but the literature on the Richmond website tells you what yoke you need to make it fit.
I have not found any info on the spec for the ROD 6 speed, but richmond does offer a 5 speed overdrive transmission rated at 600 ft-lbs as a bolt in replacement for the t-5 so if you need a really beefy transmission that may be the way to go.
