Greetings ctvaughn,
Welcome to the GMT400 forum!
****
For what it's worth, last summer I also went through the task of replacing the rear
parking brake cables. Unfortunately my vehicle isn't an exact match of yours
('99 RCLB C2500) so I can't give you the specific part numbers you need.
However, what I can tell you is that you need to know your specific wheelbase for
your '90 K1500 RCSB *and* the GVWR of your original machine. But you aren't
necessarily out of the woods quite yet, for IF the rear axle you swapped in was for
a different (heavier) GVWR, then you need to look up your truck sold in that heavier
payload (K2500?) get those part numbers, compare the specs between the 2 sets...and
if one set has the missing 5" then that's what you want to purchase.
To give you an idea of how I got the right parts on the first try, here's a link to something
I posted in my 'functional resto' thread on my chore truck.

AC/Delco parking brake part #s for '99 C2500 RCLB 8600 GVWR truck)
Disclaimer: All of the above is just general info, and I'm assuming that A) you swapped
in a 14-bolt to replace a 10-bolt, and B) that this would make a difference in the cables
required. If either assumption is wrong, then please disregard & accept my apologies. :0)
EDIT: And if anyone reading this performed a similar swap and has the specific info that
ctvaughn needs for the parking brake cables that fit, then by all means share the wealth.
Hope this helps you get this over the finish line. And when you figure out what works,
then please reply back with the specifics, so that others facing a similar snafu can benefit
from what you have learned.
Best of luck! Cheers --
