Wanted: Plymouth Duster parts(Aftermarket)

Let's help him out a bit. 340: Just because it's an 8.75 doesn't mean it's a 4.5" bolt pattern. Early 8.75 units for A bodies were 4" pattern. Look on the side of the center section and it will have numbers. The last three will either be 489, 741, or 742. If that center section comes out from the front it's an 8.75 unless someone slipped in a ford 9". Measure from the out side of a wheel stud to the center of the one across from it and there you go. Not a lot of choices for wheels for SBP. I tried for a long time to find a set of Torque thrust in SBP but went with original rallys. Good luck.
