Are all Plymouth bucket seats the same?

[cudashark]

My cousin needs seats for his 73 Barracuda. The seller says these seats are from a Plymouth but he does know what model. They look correct but are they?

Look like 70/71 , they changed something almost every year , but yes they will fit.
73 & 74 had soft backs / no hard rear panel

If you use these seats the 73 upholstery won't match the foam underneath. You would have to go with 70-71 upholstery.

Classic Industries catalog has a good set of pictures of the differences.

Looks like 70 ~ 71 seats with the inserts redone non stock
73 seats look like this;
They will physically fit though
