i'll get some pics up soon.
thanks

Are there aftermarket gears for it?(i haven't looked yet)
thanks for the info.

At one time, were was an almost mythical 3.90 gearset that was available, but they have not been made for many years. At this time, the only real solution for higher gearing with the Eaton rear is to find the elusive 4.10 3rd member from the '68-'72 3/4 ton.

Another option is do a late model rearend swap. A 14 bolt rear from a dually truck is popular swap. A Dana 60 from a Dodge/Ford van is also a popular swap too. 14 bolt http://s1074.beta.photobucket.com/u...amp;_suid=136167734275303977352668859631 | | | | | Joined: Oct 2006 Posts: 9,671 'Bolter | | 'Bolter Joined: Oct 2006 Posts: 9,671 | What are the three pictures of the ball and tapered bearings for in that album Chris?

It looked a little goofy, but it was practical for us. Here is a picture of the last one of them that still saw limited service when I remodeled my house 30 years ago. http://www.flickr.com/photos/crenwelgeoil/2847834566/in/photostream | | | | | Joined: Mar 2008 Posts: 1,775 'Bolter | | 'Bolter Joined: Mar 2008 Posts: 1,775 | Denny- The ball bearings are the oem front wheel bearing. The tapered bearings are the MBS replacements. I got them from Chevs of the 40's and Classic Truck Parts. I don't know if they are still available, since Japan has had an earthquake, tsunami, and nuclear meltdown since I've gotten them.
Ihe MBS are a tighter fit. Some emery clothe to the spindle is necessary. The OEM felt seals won't work with the MBS bearings either. The Timken seal in the picture is a pretty tight fit too. I'm going to eventually order a seal with a slighter larger ID.
