My street used Tubular K frame is getting close!

for what it's worth. I think on your build , heim ends are a must ...because the design of your lower control arm reguires the lower pivot to do more than go just straight up and down...it also has to pivot somewhat towards the front..then back....good choice for your application

can't say if the design will have an effect on the stock built in anti-dive....something else to consider....might even make it better
