CPT Reverse Shackle front mount question

Hello,

I have a 1975 Scout II and I am installing a CPT reverse shackle kit. I've got the front shackle mounts cut off and one side ground flat, but the new front mounts want to overlap a gusset(?) from the front cross member/bumper mount.

With a straight edge on the outside of the mount I can get about 1/4" gap on the outside of the frame and the inside weld area will overlap as pictured below, and creates about a 1/8" gap between the frame and the rest of the mount, so it doesn't want to fit flush.

I'm considering cutting the the gusset along the line and bending it up to reweld to the frame. Is this a good idea?

Passenger side, looking up (mind the rust):

I got everything welded up and I'm pretty happy, but I've noticed that the shackles with the hollow spacer section seems to be crushing/compressing inward while trying to torque them down to what my book says is the correct spec (60 ft lbs). Is this normal?

Can you please post a picture of the area of concern?
 
Sure no problem.

Hard to see through the narrow gap between the spring and shackle, but the inner surface is being crushed inward by the spring's bolt hole.

This pic is from the underside where the leaf spring is staring to make direct contact with the shackle.

Thanks for checking :)
 
60 pounds is probably a touch high for a plated 7/16" bolt and should be closer to 50 pounds. But surprised at 60 it started to collapse the shackle. Realistically a washer will fix the problem, but if you want new shackles sent out we would be happy to do so. Just keep the torque down as really with the supplied lock nuts a quarter turn just past snug is all they need.
 
The washer was actually what I was thinking for a quick fix. It doesn't look like any of the weld was cracked or anything bowed out, so I'm not worried yet.

I'll try the washer and start with 30 lbs this time and see if I can feel out a limit.

Thanks!
 
Those have rubber bushings in them? Seems to be no bushing exposed at all and shackles rubbing on the actual leaves.
 
Hi, yes they do have bushings, but the bushings do not extend outside of the leaf at all (actually probably set within the leaf slightly). These are rough country 2.5" lift springs btw, but seems pretty similar to what appeared to be the worn out stock springs.
 
The Rough Country 2.5" springs do come with rubber bushings while the 4" come with polyurethane. We prefer the polyurethane bushings as the rubber bushings in the 2.5" springs do not last very long and the poly ones have the extra shoulder.
