Is there anyone on planet earth that can give a step by step procedure on how to remove twin carburetors on a 1994 gtx with a 657 engine????? There are several 13 mm. bolts and also several 5mm allens> I have bent a old 13mm wrench at a 90% angle and I am able to loosen the 2 top mounting nuts! Is it possible to remove the bottom lingage on the throttle to get access to the bottom two lower mounting nuts?? If I have to remove the manifold do I loosen the allens or the 13mm bolts???????????????????
