Nope, no offense taken. In fact I just got done minitubbing and relocating the springs on my Dart and I did it the tried and true way, into the frame.

But my point is there is more than one way to do things, and there are a lot of assumptions going on about how dangerous and wrong it was to do it how this guy did it.

Yeah, maybe it only ran one 11.50, maybe it will fall off one day, maybe it will rip the frame, etc. but unless those theories have evidence, then why accept those over the theory that it is sufficient, properly welded, tried and true over several seasons, etc. Or the theory that there are other people who have chosen to do it this way (to avoid cutting the frame for whatever reason) who are not having rearends and frames ripping out left and right.

I think he just wanted some opinions and that is what he got. I would just fix it the correct way and be done with it but perhaps that will make or break the deal.

There are definitely more than one way to do things ... I say to people I work with there are 3 ways to do things , the right way , the wrong way and my ... or if someone else did it THAT ... way , 2 of those ways are usually the same.

The usual, and correct way would have the plate the both spring hangars are bolted to should be supported on both sides at a minimum, it doesn't take a rocket scientist to see that the way in the above picture is an accident waiting to happen once the right amount of traction and torque are applied.

I've seen better supported setups many would think was done properly almost ripped out, that one ..

The op asked for an opinion and he got exactly what he asked for as someone else pointed out.

There is NO support on the front hanger. (refer back to the magic word: triangulation). Actually no support on the rear either. You're right, it COULD be okay as is, but why take the risk. That is a HACK job, plain and simple.

Any other fabrication on the car (frame connectors, roll bar) of this same "quality"??

I would think that anyone with any mechanical aptitude would refuse to drive it; I know I would.

All that said, it's REAL easy to fix...

Extra credit for putting the fuel line right there to. That way when it breaks loose and grinds on the pavement in a shower of sparks, he'll be able to keep a good fire going.

I'd like to see those people explain why this design is actually unsafe-- knowing how much weight/force is on each of the 4 involved weight-bearing areas of the rearend (the front and rear hangers on each side), and that a properly welded bracket of sufficiently sized steel would fail under those forces.


This design is going to have flex... being that the
load is applied to 1 side... flex ends up causing
cracks and failure... if its boxed with a gusset
applied to the edge and running to the frame it will
spread the load and keep it from flexing.... also
flex adds in binding which can change all the time
and makes it(the car) less consistent.... there is
a magic word in chassis building... triangulation



Further to what Mr. P-Body said: (Not sure how well this will show up, will have to click on attachment and then enlarge)

Thanks everyone for your input. We are going to look at the car this weekend. This was the only thing we questioned out of all the pictures he sent, I was looking for more input than my own thoughts. Did not want to see a young man just getting into the hobby have a bad experience. Will prob use this as a negotiating place. Thanks again.

Good call..........this should knock the price down for sure.
At the end of the day , a lot of people who's opinions I trust don't think this is safe...I agree with them.
But it sounds like you have fabbing skills , so it shouldn't be too difficult to make right.
Good luck on the buy.

Putting the leaf springs inboard of the frame rails makes the roll center too close. Maybe, just maybe you could install a anti-roll bar set-up like tube chassis cars use to help keep the load even. Actually, they make a nice addition to a leaf spring car anyway, as they even out the torque loading and make the car react quicker.

I've had three cars with the springs moved into the sub frames, I've not seen any noticeable changes in the handling at the track or on the street

The closer you move them inboard it will increase
roll rate(easier for the body to roll)... weather
you seen it or not
