ok guys here my question.

i am currently putting a sbc with a th350 into my 91 fox and i want to retain the stock speedo in it and make it work. what is there that can be bought to send a electrical signal from the transmission cable drive to the speedo to make it work or is there even a thing out there that exists
thanks

 

You need vss? Or just cable drive output?

 

I may be reading it wrong here but you don't need electrical signal for the factory speedometer on a fox. It is cable driven. It's just like a 69 Camaro with the exception of it being a push lock connection instead of being threaded on.

 

ok thanks i hadnt checked yet and my brother had told me that it was an electric gauge

 

The 94 and newer speedo's have electronics involved but the 93 and older fox cars are mechanical
