With my 68 deluxe which was also originally grey with red interior, It has red vinyl on the dash cards and also rear parcel shelf... all red vinyl. The floors have red rubber mats front and back
As for leaving the seats brown... well do you want a car that looks as it did from the factory, or ones thats spent 43 years going old and crusty? Entirely up to you
Me personally, I could not tolerate that, I prefer things looking pretty.
Also, I have attacked my seats with various chemicals namely thinners, metho, prepsol.... Yes it takes a little off, I found with the particularily dirty areas where I had to scrub harder, i did find some red on the rag i was using... not a concern, just stop scrubbing once its clean! Best thing you can do once its clean, is use an upholtery cleaner to remove the chemical, then a conditioner like armoural to protect it. Good as new! This is what I did, and mine came up a treat, no damage done.
As for the current trend with restos... well I guess its really up to the individual.. It seems to me the rarer the car the more people like to see them restored to original specs... I am still struggling with this decision for my Deluxe...
