Rear leaf arch 4X4-4X2 - The 1947 - Present Chevrolet & GMC Truck Message Board Network

What's the difference between the arch on 4X4 vs 4X2 rear leaf springs?
I converted my 68 GMC 2wd to 4wd. The front axle and springs are from a 70 blazer, as is the t/case and 4 speed. The rear springs are the 2wd ones the truck came with, but I had to use 4" blocks in the rear to bring it level with the stock front 4wd suspension. Iwould like to put a 4" lift on it, but with the blocks in the back, more blocks aren't the answer. Would the rear leaves from a 4X4 make it right? And yes, adding the 4X4 front axle to the 2wd frame without another to look at or measure was a PITA, but it all works fine.
