Re: Muncie Speedo Gear Question
Wow, I think my head is going to explode. I opened up a can of worms on this one!
I guess I will try what I have and see how far off it is, then make adjustments later. 69L78 - Do you have a number on your adapter since you have the same gears and trans # as mine? Thanks, Paul

The adaptor # is 6476736 with a 1:.777 ratio and I believe the gear is a blue one with 20 teeth. [/ QUOTE ] Can you post a pic of the adapter? That sounds like the AC part number that Ed C. quotes...

[/ QUOTE ] This is the style used on the Deuces, not the square model as pictured earlier. Anybody know much about the 'key' that is used to link the cable and the adapter? I bought the 'key', but the speedo still barely turns

I could swear that somewhere I have pics of Mark Hassett's orange car when it was being restored (Nova Times articles maybe?) and it had the square type... I was thinking this car was pretty original as far as parts go.
