Dumb question but I did a search LOL

IDK about the temp gauge information in the previous post? The stock thermostat in my 72 is 195 degrees, same as posted LS temps. No way the stock guage pegs at 5-10 degrees above that. Guessing something going on with his sending unit. The LS sending unit is not compatible with a stock guage.
While I am not a fan, I believe Dakota digital has GPS speedo clusters for the 67-72 trucks. They also have digital to mechanical speedo drives and speedo/tach conversion modules. I have several parts from them for my truck. Will be using a stock type cluster.
