Do you need such a big TB on your 96 ?
What is your engine spec ?

do you need it ? I think you better get it going again first

I would buy the HPI throttle body. What exhaust are you considering because that can make or break your builds HP. The clutch will need a heavy spring and maybe a VPC depending on the torque.

 

with the HPI unit you can use any aircleaner with the s&s 58mm you have limited selection
