I am in the middle of installing the 4x4x2 steering box and have it mocked up using the rear lower original steering box bolt hole and the rear of the box is crashing into the radiator core support. I was wondering how far rearward can I move the box without having interference with steering linkages. Right now the pitman arm shaft is close to the original location of the manual box and it needs to move rearward about 1/2 to 3/4 inch. Or would it be better to clearance the core support and leave the box where it is. Either one is not a big deal at this point. Thanks, Ken
