1974 Dart Swinger

Today we tried to install an Edelbrock 14in air filter on to the stock carburator useing an adaptor kit. The problem I have run into is that the bolt that holds the air filter houseing on isn't long enough to come up through the lid. Can I replace the lid hold down bolt assembly with one thats longer? It appears to simply slide down and clip into the top of the carb. Does any one know where I can get a longer one or have any other suggestions?
