94 aod to t5 swap
 

I have a 94 GT I just bought that has a 5sp t-5 in it. But when I got it the speedo didn't work. Come to find out that the car was originaly a auto. I called a dealer and he told me that Ill need to change the ecu and the transmission harness for the swap. I just didn't know weather he is pulling my chain or what. Is there an simpler way to convert or is that the only way.Any help that can be offered is greatly appricated.

thanks jake
