factory panhard bar question

[1972BackInBlackC10]

i recently purchased a 1969 gmc short box, it came from the factory with a pan hard bar that doesnt look too strong,

im using my lowering kit from my 67 and im wondering if an adjustable panhard bar will work in the stock location or if id be better off going with a super track bar kit and a shock relocator kit?

im not sure what kind of drop is in my 67 as i bought the truck with it already installed so im not sure if a supertrack bar kit would be necessary i do have some pics in my build thread they arent the greatest to tell how low it is but i can get more pics and some of the factory panhard bar if anyone needs them

any opinions???
