Another Clutch Fork Spring Question

79 F100.. Was 302/c4 years ago. Now 460/T19 swap in progress.

Random spring parts I have



What I believe to be a 4x4 bracket

long spring was on the 79 F350 / 400 that I grabbed my swap parts from

Short spring is an NOS 302/4 speed spring.

I can't figure out where *any* of these would go.



Also, I think due to the headers, I'll need to cut the adjustment rod.



No holes in the cross member under the engine towers.



No holes in the frame that I could see.

Any 2wd F100-F150 guys have a picture of the frame side of the spring?


As it is now w/o that spring, The pedal "pops", and doesnt fully return when pressed.

Here's the illustration from the Ford parts catalog. Unfortunately it's not too clear on the front spring attach point.
It "looks" like 2WD hooks to frame or cross member and the 4WD hooks to a bracket bolted to the frame.

Yeah, I have that illustration, and yeah, it's not helpful at all. I searched a bunch, but only found either F350s or 4x4s.. Neither of which help me.

The thing is, FoMoCo didn't offer the 460 with a M/T (or 4WD) until 1983 (F250/350 only) and thru 1997, all came with a hydraulic clutch.
.
No 460's in F100's after 1976, no 460's in F150's after 1979.

I am fully aware of this.

However, I keep hearing about a mystical "hole in the frame" that everyone seems to use, but no one has a picture of. Since my frame was pre-drilled and had the mounting nuts for the equalizer bar bracket, I figured it'd be safe to assume the frame had a home for the clutch fork spring.

Soo.. where's it go on a 351M 2wd, 302 2wd, etc etc?

4WD spring attaches to bracket / 2WD spring hooks into hole in frame rail. Since your truck originally was 302/C4, there will be no hole in the frame rail.

Success! I found the hole .. or a hole.(yeah yeah, ha ha ha ha).

There was a small hole under the engine tower that the long spring I grabbed from the F350 fit perfectly. Right or wrong, it works.

I still can't figure out where that hole "would be" as there's a steering box in the way, but, meh, it works.
