I'd like to replace the throttle cable in my '74 Argosy 24. The old one is okay, but even with my new throttle body, which operates much more easily than the old Quadrajet, the throttle effort seems too high. Plus, the rig is nearly 30 years old, with 120K+ miles, and the cable has to have some wear.
My local Chevy dealer tells me this part has been discontinued and no replacement for it is available. Any suggestions on where I might find this item off-the-shelf before I have one custom made? With all the P30 chassis running around out there, I have to believe someone has a replacement for this!
Ask your friendly dealer if he would do a part search,they can link (if they want too) to all dealer data base and tell if that cable is setting in some dealers parts bin, just waiting for you.
G.M. makes so many cables, it is concieveable that a cable a little longer or shorter will work.
They make( or made) a cable with 2 different ends at the carb , depending IF you had a "holley" or "Q jet .
One had a receiver for a "ball" stud, the other had a hole for a stud that had a retaing clip.
I have cured a "high pedal effort" many a time, with a simple "helper" spring working against throttle butterfly spring.
(Just dont make it too strong) , a screen door type spring works well.

Go to Orilley's autoparts on Charlotte pike ask for Todd. He can
find just about anything for a p chassis and has helped me with my 79 excella 24 ft. Good Luck !!
Friendly dealer checked and found no stock for the cable I needed anywhere. O'Reilly's has a listing in their Pioneer line for a '78, but it's not right for my '74. It looks like the picture below (if my file loads properly).
A company called Lokar makes general-purpose cables with Teflon lined jackets, and their pricing isn't bad. They also say they'll make custom cables. I'm going to contact them and see what they can do for me.
Different than mine, it has ball studs on each end, 82" long. Keep us posted on what you find, I even tried getting a universal and couldn't find one that long. Next shot was boat cables.
Well, I've decided to punt on finding an aftermarket throttle cable. I determined that the cause of my excessive pedal pressure was the linkage geometry on my new FI throttle body. The attachment point for the throttle cable was about half as far from the butterfly shaft as on the original Quadrajet. Not only was the effort higher, pedal travel from idle to open throttle was much less, which yielded sort of a hair-trigger response - very tricky to drive smoothly. I made up a little extension lever to duplicate the original geometry, and I'm much happier with the throttle action now.
Even with its many miles and years of service, my existing throttle cable seems to be in fine shape. I think the hot rod suppliers will be the way to go when and if I ever have to find a replacement.
