If you found a 73-76 k-member you could run the narrow sway bar that will allow for big backspace rims. And you wouldn’t have to buy that special kinked Hellwig or the narrow Hotchkis.
This is turning into quite the interesting thread! I'm curious though, is this the only advantage of a '73-'76 K-member? Clearance for wheels through a narrower sway bar? Are there any other advantages to this specific part?
