I think I might have solved the "cut-pile" or "80/20 loop" carpet mystery

From B bodies only:

Question:
Ordering carpets - question ACC 80/20 Loop with mass backing verses Essex with mass backing.

This is referring to the 80/20 loop carpets -
ACC Essex -
Original factory carpet replacement.

Which would be closer to factory quality?



Answer
The 80/20 is factory correct for most cars. The Essex was used in some 1974 and up cars I think. Quality wise the Essex seems better to me. Mass backing is better in my opinion. I have had the best luck ordering the carpet thru rockauto, it always shows up fresh and without long-term fold lines. Just be sure to get it out of the box and laying flat fast.
