CAS part #'s

ive got a redtop and the CAS in it has 2 #s on it
D4Y89-01A
23731 F0501

now ive seen other CAS’s for sale online that say they will work with a redtop but have slightly different part #'s and my brothers redtop has these #s aswell, although his motor runs like a bag of shit… dont ask…

D4Y89-01B
23731 F0502

my question is what is the difference and is it possible to use either CAS on a redtop?
they both physically look identical otherwise

thanks for the help

Kyle

it’s 50F0# (not F050#)

both the same

good to go

Yah sorry those #s were memorized. So apparently I’m dislexic lol. Thanks a lot tho. Huge help! Appreciate it a lot

If needed, I have two CAS’s for sale. Both perfect.
