i know you can do it with 49-51 ford shoebox's but i dont know about chevy's, interesting question. but i dont think so.
if i remember correctly the spindle bearing race is almost centered between the kingpin mounting bosses. so you wouldnt gain anything. and the camber is going to be way off. my 2 cents
I don't believe you can flip the Chevy spindles for any effect. Try Buffalo Enterprises in your state of Washington. 360-652-7684 or Fat Man Fabrications
