Another drum > disk question...

I know this has been covered countless times. However I can't seem to find an answer I feel comfortable operating off of.
Currently I have an 85' TA with the 9 bolt Borg Warner/ open with 3.08 gears, and drums.
Im going to look at a 9 bolt, posi with 3.27s and disks this weekend. So if I am to just swap out my rear with this one, I would only have to change my e-brake cable, and proportioning value correct? Ive heard a few different opinions on this.
First post, thanks fellas

Don't forget about speedometer re-calibration.

How exactly is that done? I would just need to swap out the speedo gear from the side of the trans? Just take the gear from the parts car correct?

So the proportioning valve is located on the rear where it splits the lines? Or are we talking the valve right after the master cylinder? I should be able to swap over the parts from the other car correct? Or is there a good place to get them after market valve and cable?
Thanks fellas

Proportioning/Combination Valve is right under the master cylinder with 2 lines going in and 3 out I believe.
