Front suspensionl

[pappy 2]

My 71 S/B does not handle very well. Has 2.5 drop spindles with old front coils out of a 6 cylinder truck QA1 shocks in stock locators. Was thinking about QA1 coil overs with my spindles. Lately, considering a Heidts Mustang 2 front suspension package. Has anyone done or seen this setup in the 67-72 trucks? Checked Heidts wedsite, only found video with a later model, like 80 something truck, and they only talked about the kit, no actual installation infor. Reply will be greatly appreciated.
