Steering Box Difference '72-'73

racerbob said

So if you have access to a manual steering box and steering column from a 1972 duster, it will fit in a 1973 duster.



hope this helps,

It will, but you will also have to change to the '72 center link, pitman arm, and idler arm. In '73 the A bodies got B body steering gear, that is why your '70 B body box bolted in. The '72 and older box output shaft was just a little less than an inch and the '73 up was around 1 1/4".
