I found this whole truck with no title on the net but it is only a 4 speed, is a 4 speed any good? could i use it? what would i need to do? is the rear dif the same? also the top speed on my speed-o is 85 and this other truck its ABOUT 110.... whats that all about?
thank you

 

The 4 speed is ok, but the 5 speed will give you better gas mileage and a little more top speed because of the extra gear, that`s why the speedometer goes higher on the 5 speed truck.
