Is it a factory shifter box ? I'm not sure what year the OEM chrsyler boxes used the bushed setup, if at all considering the 80's trucks with 833's didn't use the bushings and I bolted an NOS box directly into my 69 Dart using the original factory linkage.

No the ball stud is the same length ,, you need to check front to back skewing , did an install on a 71 challenger and had to trim the Z bar to fit using a lakewood on a 440.
