I bought a one owner 70 SS396 with 53k on it. It has the factory engine and rear end. But the M-21 is gone . It was replaced with a 1971 M-22! But the shifter isnt the right one for a 1970 with console.. They hacked the hump some to make it fit. Id like to know ...what Hurst shifter it is before I replace it. Any ideas guys ?
