    I would just un hook the shocks... cut the mount loose from the rec tube..and raise the existing mount and re fab it to the rec tube thats there.. i'd cut out new shock mounts on my plasma table so that it would look presentable just measure the spring compression on load so you get it to where you want it to ride.... adding a block will look like it was wrong so you added a block also looking at the shackels you could easy remove a leaf to get the shackle angle right.. and that would lower it an inch + -

  2. Almost straight shackle. Seems to indicate a spring that might be short or wrong spring rate. Shackle length?

    there’s a lot of distance here

    also suggesting a wrong spring rate or possible spring length issue.
    Looks like a good bit to be gained in drop just here
    I wouldn’t cut or move anything until this is looked at

    Getting off the OP's subject; but usually a suicide front end refers to a spring behind axle set-up = suicide if the spring breaks and the front corner digs into the road. Kinda like what happened to the "Pale Rider" when the spring eye broke and mayhem resulted.

    I guess I misinterpreted the "not" four words previous as being related "significant".

    I have dozen or more of these axel cars.. and I say that axel is a 36 era drop... not one of my cars has that excessive amount of spring clearance...a real easy "JUST TO SEE" that I would do it is this... jack it up, let it droop frame on jack stands... un bolt the spring, take all the leaves out but the main...with just the main leaf in , to be safe bolt it up... ... with a floor jack... raise the axel up slowly and watch to see if the one leaf flattens and look at the shackles and see when they get to about the 45 degrees.... then check every thing like the tie rod... if the spring goes all the way flat with out lifting the frame off the jacks start adding leaves... i would eliminate the second longest and add leaves till you get to where you have a couple inches between the axel and the spring mount... I say you could lower the front about 3 or 4 inches with just the right spring'''

    but I know nothing about anything but how to buy cars... and I could have fixed that car faster than i typed all this.. but doing what I just typed you would find out real quick if the mount needs moved and if it will work moved.. with out having to change a bunch of other stuff.. and only a few minutes to put it back to how it was.... I do that a lot lol

    here's what I see and think.. the axel is a 36... and they ordered a new 36 ford front spring... when the put it in it looked like a g***er... so they took the 4 or so leaves out of the top of the spring.. a 36 ford is probley twice the front end sprung weight

    Like many hot rod things, there are different interpretations of the phrase.
    https://www.jalopyjournal.com/forum/threads/suicide-front-end.1045519/
    I have always felt that it describes a front axle that is located in front of the end of the frame, such that if a failure were to happen, the axle would not support the frame. This can be spring over or spring behind, although it's more 'out there' on a spring behind. It's the relation of the frame and axle. A stock Model T has the spring and frame above the axle.

    Others feel that it's the tie rod placement in front of the axle.
    If this were true, a Model A frame which extends forward of the spring mount (crossmember) would be a suicide if the tie rod was ahead, even if the horns and spreader bar were ahead of the tie rod. No I don't think many were built that way!

    There have been discussions on Ackerman many times, often touching on the efforts needed to get it sorted with a front mount tie rod.

    As far as the spring, I had to take a few leaves out. Before, I could stand on the front perch and bounce with no movement. Now it flexes at least an inch. Mine weighs 1760, with close to a 50/50 split, so it's around 900 pounds in front.

    I watched the YouTube video the OP had posted previously and noted that the front axle is a '37-'41 axle.

    Yep, a dropped A or '33-'36 axle along with a proper spring would get it down in front as desired.
