1967 barracuda bucket seat adjust

Hellooooooooo FABO.

I did try to use search function...... just so ya know.

Aformentioned 67 fastback buckets.

Without carpet in car and seat placed for first time......

Im 6'2" and my head is too close to roof.

If i move mounting studs forward, effectively moving seat backwards, i might gain a skoosh of headroom.

Any tips/tricks to stud removal before i get out the 2#?

Or....

pie cut seat brackets?

Or......(insert suggestion)

TIA
