Hello Follow 64 owner,
I have a 10 G , Convertible, it has the Burtex backed Splatter design Trunk mat.
It is a Conservator now, but I have talked to a few people, and some think the coupe had the Splatter and the Convertibles has the plaid mat.
The bag is OK but you do not need it, just takes up valuable trunk space and it is not judged.
I can tell you the Plaid is stronger and easier to clean.
On another random thought, in the trunk the WAY the jack sits is different on a 64 then a 65 I have both Owners manuals, I display them nearby for the judges to review.
God Bless,
Jake
