I’m looking for pictures and dimensions of actual original GM rear seat floor mats for 67-69 Firebirds. Reason being is I have found that the aftermarket mats available seem to be way over size for the rear floor mats. What have others found with aftermarket mats and how did u get them to fit decent.
Thanks

The originals are not a perfect fit. In this post I showed photos of an original and mats.

Note the curled edges.

Thanks for the FAST reply, U answered my question, the pictures r very helpful
