Help replacing the weird rat trap throttle linkage.
So I have a stock 69 f100 with 302 and the really weird contraption of a throttle linkage. It’s bent out of shape and some of the pins are ragged out and I have to adjust the carb by hand to get it to run, making it undrivable. Some research says that you can replace it with a traditional ball end and rod set up. I don’t have access to right now to measure because I’m currently overseas, and my time home is limited so I need help with what length I need to order before hand. My understanding is all I need is just the rod and ball ends. So what you gentleman could help me with is length I need and if any additional parts are required. I apologize if it seems I’m asking a lot but I really couldn’t find much online about this. Thanks I’n advance!
Missin AGear you need to go to you-tube and type in TheCraig909. he has a 71 f-100 with a 302.he has a complete video on what you are wanting to do. you don,t need to pre order anything. watch his video and it will tell you everything that you need to know.

He has a 159 videos on YouTube, do you happen to know which one your talking about
tpdaniels yes i do. the one you need to look for , the title is Custom Throttle linkage. it would have been nice if he had numbered his videos like some do. but he did not. you do not need to special order any thing for this. the Extremely small town that i live in population just over 10k. had every thing that i needed to do this on my 67 Mustang. i bought enough stuff to do the swap on my 67 f-100 when i swap in my 302/c4.
I made this one for my 66 mustang that I found on a mustang forum back then. 2 rod ends and a piece of 3/16 rod I believe. 2 1/4x20 allen head screws and elastic stop nuts.
There is 4 tapered hard rubber washers that are for plumbing used for mounting and centering the and mounting the rod ends to the linkage.
Works like a charm.
HIO Silver just make sure that the tape measure does Not come from harbor freight.
Ugh, don't get me started with those POS things. Guys at my work seem to LOVE them since they are cheap(or free?). I get pissed just seeing one laying around(hard to miss being bright green or orange).
Oh, did I mention I work at a machine shop? Ya, a place where it counts to be some what accurate?
Freightrain don,t sugar coat it . tell us how you really feel about harbor freight tapes measures .lol. that,s why the tape in my tool box is at least 45 years old . it,s a Stanley. made in the U.S.A. still has the og. tape in it. now having said that, the next time i use it the tape will break.

As I've mentioned before, that "trapeze" arrangement was made that way for a reason. It helps stabilize the operation of the carb when the engine's vibrating or shifting under load.
I can understand the desire to replace it. I feel the same way. But whatever you do, make darned sure that you aren't adding unforeseen problems when you modify your machine!
With a straight rod replacing it, if you break a motor mount and add some acceleration, you've got a recipe for a run-away throttle condition that could be fatally catastrophic.
If I were forced to change from the "trapeze" arrangement, I think I'd go with a throttle cable (like the later trucks are reported to have) instead of a solid rod.
When I swapped to a four barrel carb on my 70 f250, I made a straight throttle linkage. I found it on a mustang forum as well. It works good. I kept all original parts for the truck just in case but Im not planning on switching back.

Don't plan on buying a Dent as Ford outfitted them with a simple rod system. I'm sure that if there was a real problem with straight rods, Ford wouldn't have used them in the millions of them that they built.

I would be really interested in learning about the change in Ford's design philosophy, why they built the 'trapeze' arrangement to begin with (especially if it was something other than that throttle runaway condition I mentioned) and then why they decided it wasn't needed any more.
