how mch did you guys pay to have yours installed i am undecided weather to get them or not depending on installiion fees

 

how do i tell what gears i have now

 

if you car is an auto it most likely has 327 if its manual it most likely has 273. I am going to go out on limb on this one but I have heard anywhere from 150-300 for labor on a gear exchange. I would strongly recommend replacing the bearings and such as well as changing the fluid and investing in a gasket as well just get it all done while your back there it will save you the hassle.
