As far as I am concerned, this is the correct stance for a 67/68. This is a photo of my 350/3 speed column shift red/red with poverty caps. The photo is from around 1970 or so. This is how the car sat without modifications. F70-14 wide ovals which lasted all of 12,000 miles when I was 16 years old.
You were able to afford a 2 year old first gen at 16?
I know this is a pretty old post. I've been busy all summer fixing heat pumps, so haven't been around here. Sorry for the late reply. I had a wealth parent... who also didn't want to drive me to school. I bought a brand new '68 Firebird from the showroom floor. My photo is from around 1970, in front of the house. The photo is the stock ride height for a multi-leaf '68 with 3-speed. The only modifications I made to that car was a zoom clutch and the shifter. Warrantee repair on the clutch was denied for "mutilation" and abuse before the 12,000 miles was up. The second time the clutch was toasted, I had an independent shop install a Hurst floor shifter and the Zoom clutch with B&B style pressure plate in place of the diaphram clutch the car came with. The stock column shift got jammed in the gate many times, shifting from 1 to 2.
