Technical Ford V8 era Spring Perch year ID Please

Just found these in the basement, really nice, but what years are they?

 

I’m pretty sure they are late 1940 Ford. The one on the left is the right perch bolt and when installed on the axle/wishbone what looks like a shackle eye would be parallel to the axle and also horizontal. That is where a bracket for the sway bar would be connected. The tapered hole is for the lever shock link.
Early 1940 Fords used a perch bolt with a different design.

 

Thanks that is what I was hoping they were, but doesn't the spring hang off the wishbone in front of the axle? Maybe these perches are for the anti sway bar? A few photos would help, or factory exploded drawing. They go in the '39 Pickup project parts pile. Bob

 

'40 Ford perch bolts.
The wide boss accepts a shackle stud that the sway bar attaches to.
The thin boss with the tapered hole accepts the shock link stud.
The "very early" '40 perch bolts were different & scarce.

 

40 deluxe, with a sway bar attachment.

 

Some day they will go in an axle you will drop. Can you notice a difference in a car with the sway bar and a normal Ford without one? Bob

 

I have never a/b compared them but I have a sway bar I plan to install on my truck in the spring. They must do something but they sure do look spindly!

 

I'm pretty sure the Standard 40's had no sway bar and the Deluxes did. I don't think it's and early vs late thing.

 

In 1940 all deluxe had them, optional on the standard .
Yes- very early on there was different version of the sway bar mount & attachment. Early type mount pictured.

 

All 40 Deluxe or V8 (standard) 85HP had the stabilizer bar. Not the 60HP. This included commercial but not trucks.

 

Not all. My standard tudor with an 85 horse didn't have a sway bar. Wasn't what I'd call an early-production car either. Hmmm...

 

Hard to come by, at least for me. I don't think I've ever seen re-pops. So I made my own. Shoulda taken pics.

 

There were two very different sway bars for 40 this includes the perch bolts. The early style had a lot of problems, very quickly, and they were often removed and not replaced, when the vehicle was out of warranty. If within warranty Ford removed the early style and replaced with the later style. The 40 (Std) Passenger with 85HP did come from the factory with a sway bar. Below is a photo of the early 40 perch bolts and the swivels.

 

when purchased, my mostly original '40 standard coupe, (with March glass) was equipped with a sway bar.
A March build is not considered early.
As shown, now has a dropped axle & after- market sway bar

 

Thanks for all the info, hope it has helped others as well. Will a stock Ford sway bar work well with a stock axle that has been dropped? Bob

 

My '40 Std did not come with a sway bar. I have always understood they were optional on Standards and standard on DeLuxe models. We have owned this one since early 1965 and was parked for many years before that. It had 42,000 miles on it in '65.
