Re: Still Can't Find the Right Gas Cap

Stant 10704 shallow cam. it was too large in diameter to even go into the filler neck but it fit on the 71 just right. I looks like I need a cap like the Stant 10742 but not a deep cam type. A shallow cam type might work. Does anyone know what I really need??
Thanks
By chance do you know if a vented cap fits? I assume you're looking for un-vented.
