I just received my aftermarket S10 tail housing with the cable speedo connection. These have been available for about 3 years now and the reviews are good. Add a shim on the main shaft to install the correct drive and driven gears at the correct location. Then use the S10 cover plate with correct S10 shift rail with this piece and you can make your T5 work with a cable speedometer. S10 shift rails are available if you need to swap out a Camaro shift rail.
