Axle perch

[Captainfab]

The problem with those axle perches is that they are not at an angle as needed for the trailing arms. If you're not in a hurry, I've thought about making up some of these that will fit the FF14 bolt. I had a crazy busy day today and didn't get around to measuring for the U-bolts yet.

The u-bolt on my trailing arm Eaton is thicker than the ones on the Leaf Sprung 14 bolt full floater.
I went and measured again.
The axles appear to both be 3.25"
Here is a link to RuffStuff
These would only need holes drilled for the u-bolts.

Yes, I see that. They are angled on my eaton, and so the the two arches would be slightly offset from each other. Not straight across.
In fact, the arches would need to be oblong.




My latest thought was to just find a cheap junk eaton - that could even be totally shot, and just cut the perches off it.
I don't want to cut the perches off my eaton because I want to run it until I get the ff 14 bolt all ready. And even then, I don't want to go and hack-up my eaton until I've ran the 14 bolt for some time, and happy I made the swap.

I am by no means in a hurry.

Wow!
Talk about a simple idea!

I'm going to save that page to pdf and post it, just in case the link fails.

Of course, one would have to veer from Glenn's layout some, because as Captainfab points out; our perches need to be angled the same as our trailing arms.

I know I've already commented on this great post, but I figured it needs more attention. I'm planning on switching from my eaton to a 14 bolt ff in the next few weeks. I see so many threads discussing the pinion angle.
And then we see different opinions regarding the single or double driveshaft, of what angle to match. But crazy longhorn's idea resolves this; you get the new perches mounted to the new axle exactly as the original axle.
