E body throttle cable length

Can anyone tell me which E body throttle cable is close to 24.25" length overall?
I have a B body cable that length and it works good, but has the wrong end (round) where it attaches to the firewall. I'd like to get the right one w/ the square push through attachment.
I've looked online and can't find any published lengths other than the hemi and 6 pack cables and they are shorter than what I need.
I'm assuming I need either a SB cable or BB w/ one 4 bbl. cable?

I think that's the 4 barrel length

See if this helps from Mancini Racing...
