Hi everybody, I have a 1991 2+2 n/a manual tranny that is doing a noise in the left side of the diferential. I used to have a twin turbo manual tranny 1990 that I crash to death and need to know if I can put the TTdif on the n/a. Need to know if is possible and if there is going to be a diference in the ratio. Thanks in advance for your help.
