t5 trans swap?

Quick update everyone. My speedo cable showed up today and should work without any problems. It is from a 1967 mustang with a c4 transmission. The following link will help with the selection of speedo gears that are available.

The cable screws into the back of the stock mopar speedo. I had to go to Ford to get the gear and retaining clip. Just reference an 89 mustang and they will be able to help you. If your tranny doesn't come with the bolt for the speedo gear it is 1/4"-20 3/4" long. My cable didn't come with the required o-ring to seal the housing but that should be no problem for the auto parts store if you have the cable in hand. Got mine from Rock auto parts on line for $21.00 shipped.
By the way, my black & decker drill's top speed is 80 mph.LoL
I used The Tire Racks website to reference my tire size specs.
