3-speed and 4-speed shifter differences

[323GTX]

Anyone know the differences between the 3-speed and 4-speed auto shifters?

Are they identical except the 4-speed has an additional notch? Like this?

P R N D 2 1
P R N O D 2 1
(low 1 extra notch?)

Or are they different in another way?

I wish I had both to compare side by side but I don't.

Reason for asking is... I'm switching from bench to buckets on a V8 Regal. I have a 200R4 shifter. I don't want to spend the extra time or money finding / buying an early 80's 3-speed shifter for my THM350 trans if I can use the 4-speed shifter.

PS: I have a 3-speed indicator plate for the console top.

the 4 speed shifter should work fine with the 3 speed trans.

Here is the 200R4 auto 4-speed shifter...

I'm assuming the 3-speed auto shifter in a Regal/Cutlass looks like this?

Or is there something I'm overlooking?
