9in rear end swap

I have shock mounts off larger Ford truck to edit the 3 inch axle housing. They will need wider then stock ubolts. That will leave a little space between the ubolts and the leaf springs. Is this going to be a problem? Any suggestions?

I had the same situation, with maybe 1/8" - 1/4" side clearance to the springs. I'm using a GM truck lower plate that is very stout, and I've seen the Ford plates you're using, they are also stout. I've had no problems for 15,000 miles. If you have a newer engine with a lot of HP, may not be as lucky.

I found pictures showing a plate being used on top of springs that put the ubolts on each side of the springs instead of over the springs. Where can I find the plates or do they need to be made?

Some pictures of what you are talking about would help a ton. You can weld and re-drill the plates that you have to eliminate the gap if it is a concern but a small gap would not be a problem as long as the bolts are new and properly torqued.

Another suggestion - take a look at the Mid Fifty catalog for the 1957-66 parts. They have u bolts and shock mounts that allow you to mount in the stock position under the bed for the 9" that take into account the 3" diameter you are mentioning.

I asked a spring maker here in St. Louis this very question. While in the service we use to thave u bolts that were the spring width until they went through the bottom plate Where they widened. They said they couldn’t make that type of u bolt but that there shouldn’t be any problem. I still went to the farm store and bought some small spacers (they look like pieces of pipe) for a trailer and used them to close the space between the u bolts and the springs.
