Does anybody know if they make a 25% speedometer reducer for my 72 Cutlass? The only one I found is a 38% but that is too much. If so, can you direct me to the right place to locate one. Thank you in advance.

 

http://speedometersolutions.com/ They have or can build a reducer for you, or for much less, sell you the correct gear for your speedometer.

 

Thank You

 

By speed reducer, do you mean a different speedometer gear that will turn 25% slower? If so, just pull the current gear out and count the teeth. What transmission are we talking about? It will make a difference in the speedo gear that used.
Go to this site to determine what gear you need.

I am using a 40 tooth gear which means I would need 50 teeth to slow down speedo 25%if I'm correct. I don't think they make,a 50 tooth so I will need the reduction unit

 

Oh and it's a TH400, 3:42 rear end, tires- P245 / 60 R15
