I'm not sure if they'll fit... they're completely different after all. '67 had black surround with chrome metal diamond mesh grills '66 had grey surround with black plastic square mesh grills The mounting tabs are likely different.by gtojack67 - Pontiac GTO Forum
Does anyone have some quick guidelines (or even photos or link to images) about what the differences are between the 66 and 67 4bbl intakes? Much appreciated!by gtojack67 - Pontiac GTO Forum

My ride is a '67 Convertible (unrestored, bought new by my mom). I'm a regular at the Tuesday night cruise -ins at Hopedale Mall in Oakville (3rd Line & Rebecca).by gtojack67 - Pontiac GTO Forum
I'm thinking that cover would fit a '67... maybe we should talk? :-Dby gtojack67 - Pontiac GTO Forum

One thing I did do was put in headers... I think in my case these are the real problem. They release so much heat! I've got the original exhaust manifolds and will have tby gtojack67 - Pontiac GTO Forum
