I know this is beat to death, but my search led me nowhere.
Tremec 3550 plus 4.10 gears, what speedo gear? I've got an original 140mph speedo that i really dont want to go wasted in my car. Also, where do i buy the gear?
Go here and fill in the blanks...http://www.hanlonmotorsports.com/t5speedo.asp The gear chart is on the page once you fill in your tire size. Hanlon will sell you all the parts you need to do the job.
