I forgot to bring this up earlier in the thread and figured it was worth mentioning now.

The original Eaton rear end has approx. 3” o.d. axle tubes whereas the 14-bolt has 3.25” o.d. tubes. The larger diameter tube interferes with the U-bolts due to the trailing arm angle (not perpendicular to the axle). And as such requires some clearancing of the axle tubes with a die grinder to make the U-bolts fit. I removed about 1/8” of material from each side where the inside of the U-bolt touches the axle tube. You can see in the pic below how the axle tube is larger than the distance between the U-bolt holes in the perches.

Like I said I forgot to mention this before and another member who was doing a similar conversion brought this up as a concern.
