Pro street frame question

[srt cummins]

Truck is a 1500 single cab ram. Going to do a 4-link back half from the front of the bed. I want to do a mustang II front end. How much of the original frame has to be left?

I'm not sure that all orgs are allowing full replacement front-half suspensions. If they are, then you'd need to have a section of original frame rail under the cab. I suspect from the firewall to the rear cab wall would work.

Thanks. That's what I will go off of then. Worst thing that can happen is they you can't race in this class.
