hi guys ! i wanted your advice for a trade that i want to do .. i want to trade my 74 cuda who as now a 73 340/727 for a 75 duster 318/727 ..

the cuda is a project car but complete , when i bought it it was already parted out .. the diff 8 3/4 3.23 is still there and as the complete interior
the car camed original with a 318 and was b5 blue with a special edition blue interior ...
