I didn't have that "option" on the Shelby

 

so call me dumb but im looking to put a sr20det or even better a rb25det from a skyline in this car because the way the research is goin, im gonna be refabbing half of this car anyways so y not make this thing a full on drifter. what i cant figure out is which rear end is the best for something like this. there are so many options when it comes to rear ends, i guess ill hafta see what my wallet says come decision day. ill keep everyone posted on the build. thanks for all your ideas/comments

 

I used a 9" ford , but that was cause I found a narrowed one that fit perfect for very little $$$
