Mech Smith's Speedo bouncing a little?

On my Toploader the cable snakes through a hole in the emergency brake handle bracket and I concluded it would be toough or impossible to pull it and the gear out from underneath. So, I will have to pull the transmission tunnel eventually.

In 20 years I'm on my 3rd cable. I think I've had 1 plastic gear at the trans end strip. I had one geared reverser at the speedo end fail.

Although the current set up has lasted about 5 years, I still get some needle bounce below 15 mph.

Before spring, I plan to purchase an electronic programmable Smiths gauge from APT Instruments Inc. It eliminates the cable, and uses an electronic pulse sending unit.

It will come out and the gear can be replaced no problem from underneath the car. No need to remove the tunnel. i had it out 3 times in one weekend. A little frustrating and not the easiest thing to do, but very doable!

Is your's run through the parking brake lever mount plate? I'll take another look at it but it sure looked like I would have a difficult time getting it out of there due to the tight space between it and the transmission tunnel.

I don't remember because it was over a year ago. I cant get it on the lift for a while because my mustang is dead on it at the moment. It did go thru something that was a PITA, but I do not remember if it was the parking brake or not. When do you need to know by? I will be doing a bunch of work on it this winter and I can give you a definite answer as soon as I get it back on the lift

David - no hurry. My speedometer is doing better with the work I did on it. I will probably try to pull the plastic gear this winter to check it and may try to pull it from underneath first. If that doesn't work for me then nothing ventured, nothing gained - I'll pull the tunnel out.
