Dana 36 year interchange
Looking on ebay I found some dana 36 rears. Theres a local guy with a few but they are listed as 84-87. Some other ones with broken cases, etc are listed for 84-96.
Which is correct? Can I use an '84 assembled center section (chunk, housing, aka etc) in my '93?
Heres one that says 84-96

I just bought an 86 D36 w/3.07 gears from another member here to put in my 94. He told me before I bought it that there are 4 threaded holes in the 86, 2 on each side, that are 10 mm that will have to be redrilled and threaded to 12 mm for my 94. Beyond that everything else wil fit fine.

So anything except the 84 will be fine? Just a minor modification to the hole size/thread etc.
Now I need to decide on ratio. Is 3.07 a good difference over the 2.59? Its a .48 difference which I know is significant but it still results in a 3.07.
I can swap gears in my existing housing and was thinking 3.54's.
It's just an around the town cruiser so low end performance and acceleration is more important than top speed.
And I also understand the governor will need to be adjusted, speedo gear, etc.
Suggestions are welcome.....

FYI, The governor works off the transmission output shaft RPM it will not have to be adjusted. The speedometer gears will have to be changed to match whatever rear gear you choose or you need to add in an electronic speed calibrator that will change it for you.

An easier example is putting big tires on a truck, it will shift later and sometimes not even go into 4th. (assuming it's a truck with a 700R4).
So you don't have to adjust the governor, but it's my preference to adjust it. It needs to be adjusted now in stock form in my opinion.

I built a 3.54 about 4yrs ago. I didn't install it because I thought it would scream on the highway. My u-joints went so, this was the time to do it. I just put it in a month ago. I wish I did it sooner. It's like driving a whole new car. If I knew better, I would of gone with a 3.73.
Just my 2 cents

I usually adjust the governor with a gear change. When numerically higher gears are swapped in the output shaft turns faster at the same mph as it did before which makes it shift at a lower rpm as it did before. Which I can't stand because it'll shift through the gears too early.
An easier example is putting big tires on a truck, it will shift later and sometimes not even go into 4th. (assuming it's a truck with a 700R4).
