I am putting this here because it pretains to everyone of you running a 4L60E, 4L80E or any other electrical speedo output. Much more defined target base.
I had just put Autometer guages in my truck utilizing the electric speedo from Autometer. I have somewhere around 50miles on the speedo unit (Can verify when I get home) and have decided to pull the 4L80E and put a glide in my truck.
If any of you are looking for a speedo that will work for you, I have one to get rid of.
This is the one I have which sells for $230:

This is the one I now need which sells for $110:

If any of you are willing to buy the one I now need and ship it to me, I will be happy to send you the much more expensive speedo..
