What rear control arms?

Anybody have any suggestions on what rear control arms to get. I just got a sweet deal on a Detroit True-Trac, and I'm going to rebuild an 8.8 I got out of an 89 GT. I've got new 3.73's and the new diff ready but I was thinking I might as well put new controls arms on now since I'm gonna have the whole rear-end out of the car since I'm swapping from a 7.5 to the 8.8. Also, should I go ahead and reinforce the torque boxes while I'm back there? What kind of brake line problems am I going to run into with the swap? If anybody has got some good suggestions let me know.
 
THESE are my favorites :nice:

AutoWeld has some nice arms, too. The regular adjustable arms are about 1/2-way down the page

Then there are the affordable, non-adjustable sets like THESE from JD's Performance. More than adequate for a daily driver. Huge improvements over the stock arms. I have a similar set from Factory Five and the only reason I took them off was to install an Autoweld SuperStang 9" setup. I'm thinking about putting them on the notch since they're just collecting dust at the moment anyway.
 
I ran the Metco's and they are very nice, pricey but they are very strong and work well.

Is this a Drag or Cornering suspension? I know where you can get a nice TQ box re-enforcement kit :D
