Yeah,the linkage,motor,and arms are different for standard and hideaway.
The motor is the barrel shaped one for hideaway(regular is square)
The linkage is also different(recognizable visually by three bolts bolting the wiper pegs on,for hideaway,as opposed to two,for standard.)
And the (one?)wiper arm has an additional added sub arm(for hideaway)to it.So,instead of a one piece wiper arm,its two piece.
And lastly,lol,for the early years(70-73),there is an addition mounting plate(hideaway)that goes in between the motor and firewall.
