wiper motors

[mauve66]

the 1st gen has a variable speed wiper motor, i here 2nd gen guys talking about 2 and 3 speed motors are any of these compatible since 1st gen is so hard to get
and what about the switch and knob side inside
my sixpak cleared the original wiper but i heard some say the 69 1/2 RR/bee had a different wiper motor due to the air cleaner, was that due to the taller block?? i will be going to a RB block eventually so i need to plan ahead

On a first gen, the linkage is the same 2-3-variable.  Difference (obviously) is the motor and the switch.
What do ya need?

i figure when i put things back together i don't want to dig under the dash again if it goes out 1 day later.  did a short search for rebuilt/new ones but didn't see them yet, just wondering what i can replace it with.
i don't care about the "correct" look in the engine bay but am hoping for the same knob on the dash if its compatible with later switches.
i haven't gotten to this step yet, just another thread i was reading that started me wondering about wiper motors
