Speedo gear choices ASAP!

[mag162]

so I went ahead and had a 489 case with Richmond 3.90’s swapped into my wagon.
Driving her home yesterday my speedo was wonky as all get out!
Anyway I didn’t take into acct the speedo gear.
I’m running 27” rear tires and a 727.
I’m assuming the 727 has the stock speedo gear in it which came with the wagon and the 2.76 open rear. But I don’t know what that is.
Any suggestions?
And yes I’m considering an over drive fix as soon as I sell a kidney to pay for one of the options listed in my other thread!

Or simply go to a 3.21 rear.

The above was a good example that Mopar Performance Rag and C-bodies are not harmonious.

There is a chart, and in the old daze anytime I was under a Mopar at the boneyard with a transmission in it I'd yank the speedo gear, ended up with a whole box of all the colors.

Google Google Google. One minute.
