PST HKS k-member replacement?

i am looking into the PST K-frame replacement HDK Front end suspension upgrade kit. Has anyone on here installed this? If so, please give me the good the bad and the ugly.....

My plan was to install this kit in my 68’ barracuda. Looks pretty straight forward online BUT as everyone knows “bolt on” is not always bolt on.

Thanks in advance for any info/help!
