Default Chevy II leaf spring question

We are having some problems with the front end of the leaf spring moving. I think it is the
Frame where it has the big hole on the outside and it uses the big cup washer is the problem we tried to use aluminum spring bushings and we could not get them to tighten up so we switched to a polyurethane bushing and it tightened up but it is still moving and letting the tires get into the spring. Any help from anyone?
Thanks

If you're talking about a '62-'67 deuce, I just asked the same question on a nova site and got a good answer. They machined a washer out of 3/16" plate with a "step" in it that fits the big hole, then welded it to the perch. I'm going to do something like that on my stocker project.

Nice picture, We have a 67 Sedan we run at Super Chevy Events in the DOT class. we are having problems with the front of the springs moving. I think that is what we need to remedy our situation. I think we may plate both sides of the frame where the spring eye goes into the frame where that large hole is.
Thanks

Check the hole in the plate for elongation.........if it's worn nothing stops the bolt from moving forward and backward in the sloppy hole. You can weld a plate with a properly sized hole over the worn one and then the bolt fits tight with no slop.....

YUP......... I just put split mono's and caltracs on my 66 nova and both sides holes were badly worn out . I did a similar fix as Rich described and its better than new.

We ran into one of these at the shop where that entire front spring perch/cup was loose in the chassis. The spot welds had loosened or torn and you could move the whole thing, it had also torn vertically, you could move it back and forth. Hard to believe, but the entire thing is originally just a sheet metal structure spot welded into the car in a few spots up inside and is really flimsy if you ever see it separately. I'd suggest doing some fabrication and creating additional support and reinforcement if there's any horsepower going through it, there's really almost nothing there. It was engineered for a four cylinder back in 1962 and never upgraded, from what I've seen on that car....Amazing that they put the 327/350hp combo into that flimsy setup....
