1968 Barracuda Notch - Plano, TX

Things have been a bit busy with work and life this year and did not get much of anything accomplished on the car. Just returned last night from a week working in Singapore. So far this year I have been to Singapore twice, Taipei, Tokyo, Paris and New York.
I have the same car and it is all torn down. Starting to mock things up, still waiting on the engine. My question is. Do you think it is possible to fit a 275/35r18 in the front of the car. Car has stock spindles and 1.03 torsion bars. Any held is greatly appreciated.
Thanks
