I have a 68 short bed gmc that is now a chevy. it came with a 250 strait 6 that has been replaced with a 496bb. my question is does any one know what the gear ratio of the 12bolt might be and if any of them were posi. I looked for a tag but did not see one. any help would be great. also has any one on this board preformed a body drop on one of these trucks. Id like to keep the stock rear end and I converted the front to 5 hole disk but I am looking to find some 6 hole rotor so I can be 6 all the way. thanks rob
