55.2-59 329354 RH spindle question

[MALIBLOC]

To achieve the slammer look I like in my truck I’ve had to bottom out my coil overs and let’s just say the ride is ok and I get a loud knock when I hit a pot hole , so I called CPP and I’m looking for a 2-2.5” drop spindle so I get get the lowered look but get some bump out of my suspension! So the numbers come back as a G-body spindle or a camaro spindle , so I’m assuming I just buy drop spindles for either and theyll work right or would the spindles off a factory c10 work minus the fact that I need a 5x4.75 bolt pattern
Curious as too what some of you are running .
