I found one for a good deal but I'm not sure if it will work in my car or not. I found an article about putting a tremec T56 in (which I assume is at least a similar transmision if not the same), but I've heard that there are some where the shifter will not fit at all. Anyone have any experience on this and can let me know before it gets sold? Also, any idea what the gear ratios are likely to be in that?
Thanks for any help that can be provided.
