Hey new here looking for some help

'72 is the first year for the ''cardboard'' one piece head liners (which were actually some kind of cheap ''fiber board'' with thin vinyl glued onto them). The '72 a-bodies in general are kind of a mixture of '71 and '73 parts and accessories if that makes sense.
The ''cloth'' head liners are a lot cheaper to buy these days, but installation is a PITA unless you know exactly what you're doing and have done a few......
Just my 2 cents.
