Jim...I just got off the phone with tech. I am surprised they were there!
The tech told me that the 4:10s take a series 4 spool
and the 4:30s take a series 5 spool.


Thanks for sharing the info.
Motive never replied to my email with those questions.
My Dart has the same Strange 5 series (4.56-5.xx) spool as your car, so the 4.30 gears would fit.

I hate that term "4 series"...
Because the low number carrier fits 3.xx-4.10
and the high number carrier fits 4.56, 4.88, 5.xx
So they both are "4"
I prefer to have them say 3 series or 5 series for Dana 60 carriers.
