If i went 1tons i would not go through all that time and work to put a d44 under there. Dana 60! I know some tacoma guys do it because of the drop and the lug pattern and because they cant use a toy axle without a lot of work. Not really sure if a 44 is even stronger than a toy 8inch?
Semi-float 14bolt. They are smaller and more compact than the full float version (9.5" ring gear vrs 10.5"), physically they are about the size of the 12bolt but stronger. You can find 6 bolt versions in late 80's, early 90's light duty 2500's and 88 - 12' hd 1500's.
Its that or a 9" ford then put ford outers on your 44 and run 5 bolt wheels
They are not as strong as the full floaters but they are still dam strong. You will not break it with 35-37" tires and a 4cyl without some major abuse. They come in 8 lug versions in most all 80's era 2500s and I have seen more than one of those beat to death as work trucks / weekend toys with no failures. Also keep in mind that is what is under h2's...and they hold up...so if it can tolerate a 7klb pos witha 300hp v8 and 35s I thinl you will be ok.
Just stick with what you have for now and get the front done. If you decide down the road to change the rear you will have more time into doing the research on what will work. If you are that worried about the rear with 35s and a 4 cyl you can get chromo shafts shipped for probably $250. I don't think there will be an issue with your rear axle right now though. That will allow you to maybe spend a few more dollars on the front without having to cut corners. ARP studs, etc.
I would stick with your yota rear axle, I've beat on mine for years and only recently broke my lock right that was 12 years old. Prior to '07 I ran 35s and have been running 36" Iroks since. But if you do go with something else I might be interested in your rear axle for the right price.
