Most hairpin set ups attach to a bracket that hangs lower than the one shown above. ( not my car).
I believe the lowest part of the hairpin is lower than my low point 4 bar.
From a engineering stand point ... the 4 bar is superior ... because of the 4 moving points verus only three for the hairpin. The 4 bar is a parallelogram. Caster is more consistent.
I will agree that a hairpin setup LOOKS more old timey and traditional and can be SAFE.

Can't disagree that the caster is more consistent, but I based my choice on my understanding of the history, which R&C compiled quite well some time back. http://www.rodandcustommagazine.com/...ils/index.html
As I understand it, the front links, panhard bar and steering link all form a system, and with a cross link steering box location the problems of bump steer are minimized. Given that a dropped axle front end only has maybe +3" of travel, and that the ideal caster is a range of 6-8 degrees for a road car, the change to caster is not as critical as it once was, especially if you are running radial tires. For me, the choice comes back to the look as much as the function, assuming that you have the steering question addressed. Mine's being assembled as a drilled I-beam, Vega style cross steering, and hairpins mounted through the frame rail, because that is the look that I like. I hope that I don't regret it.Roger
Enjoy the little things in life, and you may look back one day and realize that they were really the BIG things.

I have owned cars with both 4-bars and hairpins and can't relly tell the difference in ride and handling between the two. I believe the small amount of caster change in an early ford front end is of little consequence.
I personally like the look of hairpins even on a full fendered car. My rpu sits pretty low and has long hairpins on a small tab under the frame and has been no problem with ground clearance.
I would go with your personal preference, 4-bar or hairpin.

That is the COOL thing about Hot Rodding ... rather than restoring
As long as it is safe ... there is no specific " correct " way.
I have owned 32 Fords since the 70's and the ones I had with a hairpin did not ride as well as my 4 bar equipped Deuces. If the frame mount for the end of the hairpin is on the lower part of the frame rails ... that is the better way for doing hair pins IMHO. But a LOT of hairpin setups use these aluminum brackets ( which are safe ) but ground clearance suffers.

I have never seen the aluminum brackets. Who made them?“Ability is what you're capable of doing. Motivation determines what you do. Attitude determines how well you do it”--Lou Holtz.

Years ago
Every HOT ROD magazine had ads for them. They were made by PSI Industries I believe. Honest Charley's sold them by the hundreds.
( Honest Charleys was like Summit Racing and Jeg's are now .. Major mail order supplier ).
With the three bolt holes as a pattern, it made drilling a frame almost mistake proof and the brackets made installing front ends easier
for those who could not weldI bought and installed 3 or 4 sets ... 25 to 35 years ago.
There are always a few sets for sale on eBay ... NEW
____________________________________________
This was a typical 50's/60's 32 front end setup ( the 32's above )
Some used a stock wishbone and split it while the " MORE " $$$ crowd bought the hairpins. The really $$$ crowd bought CHROME hairpins.
Below is another very popular bracket ... back in the day ... same as the aluminum PSI in function, but easy to made at home ...
but they were available over the counter also. The metal ones ( non aluminum ones ) look even more traditional IMHO.

My 3 window is being built as if it would have been built back in 1964, with a lot of help and great advice from Deuce along the way. From the outside only parts that were available back then will be visible. Although 4 link was available 44 years ago most people were still using hairpins, as am I.
Mine are mounted about an inch up the frame rails which gives plenty of ground clearance as can be seen in these pics.
That's the only way to mount them as far as I'm concerned. There's no chance of a weld coming apart or metal fatigue causing a lower bracket to fail.Last edited by Rufus; 12-20-2009 at 08:09 AM.

Thanks for the feedback. I might check out that shop the next time I am in Vero Beach.“Ability is what you're capable of doing. Motivation determines what you do. Attitude determines how well you do it”--Lou Holtz.

I saw last night on fb about John. The world sure lost a great one. I'm going to miss his humor, advice, and perspective from another portion of the world. Rest in Peace Johnboy.
