I use a cable x and it works pretty good. Not the best, but a good option for those of us who like to keep it looking stock.

 

I swapped a T56 into my '84. I started by buying a 1987 cluster and a VSS buffer box. Then I added a Dakota Digital SGI-5 into the mix. Because my car was an early third-gen I then had to re-pin the cluster harness: 19 out of 20 wires needed to be re-routed. In addition, I needed to rewire the parking brake switch to the remote hatch release. I also had to find and wire in the clutch switch for the starter circuit. I left the reverse lockout solenoid unconnected, but I think that I might buy a Basic Stamp 1 PIC and set it up to watch VSS buffer activity, and arm the solenoid whenever the tailshaft of the transmission stops spinning. That way finding reverse will be a little bit easier.

You also need to cut out the shifter bracketry from the top of the transmission tunnel then cut yourself a hole that goes about two inches farther back than the T5. You'll need to get the T5 shift bezel for your Camaro along with the shift boot, which will also sit two inches farther back than the T5 application.

Cutting the holes for the clutch shouldnt be much of a problem, but installing the pedal assembly might be an issue. My car had a cutout template build right into the sound deadener padding and that made it easy to see where I was supposed to cut.

It helps to remove the master cylinder and brake booster when doing the swap, as well as the combo valve. That way you can see everything. In addition, you might find (as I did) and it is easier to install the bell housing onto the engine first, then bolt the transmission to the bell housing.
