Burb lowering questions - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Got a 70 burb. installing Old-school Chisholm front tubular upper and lower control arms. The Chisholm lower control arms have a lowered spring pocket that lowers it about 2.5 inches. And unknown drop springs that will lower it an additional 1.5 to 2 inch. Was thinking of getting 2 inch drop spindles. Is this too much drop with a stock crossmember??

Also how much drop in the rear can I achieve before I will need C noches? I have read anywhere from 5 to 6 inches max. Id like to do airbags but may start with springs and concentrate on my LS swap I have planned for the spring.

Is it better to use stock springs and lowering blocks or just springs in the rear?? Any input would be appreciated.
