Technical Front "C" Notch on Model A Frame

Did a search and found lots of info about the rear but nothing about the front on an "A" ch***is.

Building a '26 T coupe and sitting it on a Speedway Model A frame. Wanting the front a bit lower and considering a "C" notch on the front frame rails. Already has a reversed eye spring, don't want to step the frame rails. Currently in mock up with the main leaf only and the top of the leaf is hitting the bottom of the rail and I'm still about a half inch high on the frame rail from where I want it to be (not considering the additional leafs that will be put back in later!).

How deep can you safely notch the side rails if you re-box the area (over the spring) after rail material is removed for spring clearance? Only thing putting any load on the frame horn in front of the notch will be the shock and headlight.

Thanks,

Something there don't look right at all. Do you have a spacer above the main leaf to represent the total spring pack once done? That in itself should move the main leaf down and away from the Frame around 2.5".

Notching the frame rails isn't new, look thru any street rod magazine and you can see examples of how it's done. Is the frame boxed? You may have to do a deeper cut on the inside frame rail to clear the spring. As Pist mentions, the spring does seem very low, the last thing you need is the frame bottoming out on the spring.

 

One thing I learned by doing this over the Years is to make plenty of room on each side of the main leaf if you in fact need to do it. Exact mock up and building locations aren't always where things end up once your ready for a test drive after an alignment. Give yourself come clearance for adjustments.

Deeper cut on inside of rec. tube frame as well as a 3/8 plate welded on inside from in front of spring to behind shock mount plate. The panhard bar plate was also welded to frame. Actual shock mount bolted to it. Spring is a Posie with reverse eye. Engine a 425 nailhead. Never touched.

 

I pie notched my frame rails where the front spring travels from the inside out, and the used a piece of channel to reinforce the cut. HRP

 

When you stack more leaves on top of main leaf you will have more room before it hits the frame.. The extra leaves are shorter thus making more room for travel.. A little notching is still a good idea...

 

You caught it. Don’t do things in the middle of the night with no sleep for a couple days. Spacers to replace the spring big stack are all below the spring. Still think I’ll put a notch in the rails. They are 2x4 with a taper to 3 at the front.

Thanks!
