External Tranmission Question

Is there a device to plug the hole for the speedometer cable? I just got a 5-speed to replace the trashed 4-speed that was in my '79 racecar. I don't need the speedometer cable in the car since it's a racecar but there's a hole that needs to be filled in on the tranny. I tried taking out the original threaded thing that lets the speedometer to screw onto it, but I can't figure out how to get it out.

Help!

Go to the junkyard and get the part that screw into the speedo gear assemnbly. It means you have to cut the entire speedo cable. Then use a quarter to block the hole (or something similar), then install it. I havent done it but thats an idea. It will make it clean. This is just a pocket-item iso it should be free.

Yeah, Im a junk yard hacker.

Not sure I follow that completely but I think I get it.

I have the speedo cable and the piece that goes in the tranny;which is what the speedo cable threads onto. The thing is I can't get the piece that goes into the tranny out of the old tranny and into the new.

I am thinking of just corking it with a round piece of rubber or something and seal it in there with silicone glue or something, but I don't really want to do that.

I love j-yards too, but all the ones near me are just full of nothing cool and everything lame.

Thanks, Bob

I've been chewing on this and the only idea I've come up with so far is to hook the cable back up. Maybe if you cut the mounting nut off the cable and epoxyed a blank washer in it, it might seal it up.

Edit, and everyone beat me. lol

Thats not a bad idea. I'll run that past my Dad and see what he thinks, I'll probally do that if I don't get any other ideas.

Thanks, Bob

I woulld go to a self sevice junkyard and cut a speedocable off a little bit away from the trans connection point. Pull the little pice of cable out and discard it. If you plug the hole in the cable housing with something RTV, Epoxy, or even a sheet metal screw it should work.

Those are some good ideas. When I'm at the shop tomorrow I'll see what would work the best.

I want to see what Weed Wacker did to his IT car before I do anything though.
