throttle linkage

I was wondering if anyone has changed the throttle shaft style setup to a cable? If so how did you do it? and do you have pics?

The truck is a 79 f150 that had a 300 six, now has 390.

Find a truck, 78 or 79 in a junk yard and take it all out.

So you need everything from the peddle to the carb? or only just firewall to carb? That was my main reason for asking too, i wasn't sure if the whole setup was different.

Thanks

Be aware that if the accelerator cable snaps, you may have a problem finding another.

There are FIVE different cables used on 1974/79 F100/350's, they do not interchange and all are obsolete. Only a few can be found NOS.

D4TZ-9A758-E = 1974 F100/350 240 I-6 & 1974/76 F100/350 300 I-6.

D7TZ-9A758-A = 1977/79 F100/350 300 I-6.

D9TZ-9A758-C = 1979 F150/350 460 w/Speed Control.

D9TZ-9A758-B = 1979 F150/350 460 w/o Speed Control.

D9TZ-0A758-A = 1979 F100/150 302 & F100/350 351M/400.

The cables used on 1965/66 F100/250's, 1973/74 & 1975 and later Econolines, 1980 and later F100/350's are not the same.

I personally think the adjustable rod style has a better feel than the cable set up. Both my 76 & 77 are the rod style & my 79 has the cable and like numberdummy said finding the right length cable can be a PITA! and yes the pedel has to be changed if you switch. the cable style sets in a V-channel where as the rod style snaps on a peg

You can put a Lokar throttle cable on just about anything.

Agree, it has a more responsive feel, also, it will never stretch or break.

Sounds like you have a bad clip or improperly installed. If drivetrain twist is excessive, I'd be checking engine and tranny mounts.

You'd need some very serious twisting of the motor to pop that throttle rod clip off the carb, we're talking broken motor mount, i've never lost one, if you have, then something's wrong.

Maybe the time it did it the clip wasn't clipped correctly. But I can feel throttle change in the peddle, And the engine mounts are bolted, and welded. I'll have to take a look at the trans mount.

These weird clips are right B7A-9825-B and left B7A-9826-A specific. The same two have been used on all sorts of FoMoCo vehicles beginning in 1957, also used on other makes, can be bought from autoparts stores.

The clips are spring steel, when they loose tensile strength, can pop off the rod. Time to replace the little charmer with a new clip, cuz it's 30 + years old.

Want gen-u-ine Ford? There are over 500 of each side available NOS from FoMoCo Dealers/obsolete parts vendors.
