I have a 91 LS 400 and I just recently bought a mass air flow sensor adaptor (made by Spectre Performance) from AutoZone. It specifically stated on the back that it would fit the 90-94 LS 400 models. After removing my stock airbox and air filter, I tried to install the metal adaptor to my mass air flow sensor in order to put a 3" cone filter on it. The adaptor did not fit AT ALL! Either I have a different mass air flow sensor or the company who made the adaptor is a lie!

I drilled new holes in the adaptor but it's still ghetto-rigged to hold on to my mass air flow sensor and I think I've got some air escaping through it. Here's a pic of my intake setup:



You can't tell from the pic but that mass air flow sensor adaptor that my cone filter is hanging onto is so ghetto-rigged. I need an adaptor that will fit but I'm not sure who to buy from on E-Bay or where else to buy one and I do not want to spend a fortune doing this. I need a gasket and an adaptor that will fit my mass air flow sensor without any alterations. Can any of you help me?
