A body big block power steering gearbox

P/S was not an option w/383. I was there in 1968 when I ordered my car from the factory. However something changed in late '68 because I now own a late '68 (June 1st) cuda w/ 383 and factory P/S. I have been told that the difference is in a re-designed K-member. You better check this out before you proceed. Good luck.
