Front End (frame) replacement questions

If the scamp had pwr steering and air it may very well have the same t bars that a 318 car would have. Check the numbers is the only solution.
You can put the shaft out of the scamps steering column in the barracudas column but it aint easy. The lower bearing assemblies are different. That power steering box wont work with the 67 pitman arm and drag link either but I assume you are using those parts from the scamp also.
