adjustable trac bar? What to use!

[losthope]

OK I bought a small adjustable trac arm that bolts to the stock mounts on rearend and frame rail when i static dropped my truck, I then decided to air bag it ,I used the basic bolt in c-notch and raised my bed wood floor a 1 1/2" to allow the rearend to sit all the way into the c-notch ,the problem I have is that the travel of the side motion of the rear end is still two much and at some point either with the suspension moving or me riding at different heights with the air bags the rear drivers side tire is rubbing the bed and chewed up my inside side wall , I can hear it sometimes when making a sharp right turn...so i know i need the longer trac bar that mounts to the passanger side trailing arm....my question is which one will work best for me? the CPP or Porter built? I have 0 income at the moment and had to sell stuff on ebay to fund buying the new trac arm so money is a factor and there is some differences in trac arms and cost.....

So heres CPP trac arm that cost's $109 and bolts to the stock frame rail mount and then to the trailing arm:

Then heres porter built's trac arm that costs #149 that mounts to the trailing arm then they give you a new mounting point that bolts onto the frame rail which lowers the mounting point :

I'm no expert on design but in my average joe mind the porter built looks like it is the better design with the lower frame rail mounting point because it mounts the trac arm level and would offer the least side to side movement with what ever ride height i decided to ride at??

I guess my question is would my problem be solved with the cheaper CCP trac arm that mounts at a angle from the stock frame mounting point to trailing arm?Just wondering if anyone has had any experience with either of these trac arms...if not for being flat broke i would just buy the porterbuilt, but hoping with shipping that it doesnt put me over, and why im considering the CCP and might be able to buy a replacment tire also but would hate to have to find out it doesnt fix my issue and have to end up buying the porterbuilt anyways....

just need a little insight? thanks guys
