How much would it cost to have a factory type rear schakle hanger made? It would need to be longer than factory (sit lower) hanger by 1-2" in order to use a longer (drop) schakle for more flex but no lift. Could you also make the same size as factory but offset to the rear like your flip kit to use 56" spring in a stock K5? I would like to keep my K5 stock height but gain flex and a softer ride. Thanks.
