70-72 Duster parts wanted

Girlfriend and I picked up a nice 70 Duster. Want to add a few cool things to it.
1. Sport mirrors
2. GULL wing
3. Small bolt pattern 15" Centerline. 15 x 3.5. And 15 x 8.5 with a shallow back space.
4. Chrome Direct Connection valve covers for a big block
5. 340 Torsion bars

I'm in Harrisburg Pa.
I have decent D.C. valve covers b.b. and 15x8.5 sbp centerlines but no 15x3 .The 8.5 wheels were on the rear of both my 68 Barracuda and 74 Dart Sport (sbp 8 3/4)
