70 k/20 14 bolt swap questions and concerns - The 1947 - Present Chevrolet & GMC Truck Message Board Network

On my swap from HO52 to SRW corp14 I came up about 1/2" shorter yoke to yoke using zero rates on 1" setback. I made no drive shaft modifications. And definitely, dial in the perches for the pinion angle if you have to weld perches. But just for info sake, a one ton SRW corp14 will bolt directly into the K20 with only shock tab relocation. If you have a line on one of those with the right gears its a quick job.
