Rancho RS700MT shock question? I'm Stuck

[PasoStepperProject]

good Morning all,

I want to use the Rancho RS700MT shocks on my 76 GMC K15. its lifted 4". I have some brand of EZ springs all the way around, they came installed on my new frame.

when I search for parts # I can not find the Fronts. Rear is not an issue. I even called Rancho and he gave me a part # that they say will work. I cross referenced the part # (RS7008) I looked up the shock and its for a Doge and other vehicles.

my question is I heard on one of the forums that stock rear shocks will work great for the fronts with 4" lift? Does this work? Will the ones that Rancho reccomended work up front? I'm worried about bushing size on them! I found stock rears and 4" lift rears at Rock Auto. Can anyone steer me in the right direction.

my buddy is running the 7000MT on his lifted jeep and it rides so awesome.

thanks for the help. any other suggestions are always welcome.
