This would now be the third vehicle I have seen with this combo.
I'm inclined to think my car has the wrong color seats but then again why go to the trouble of changing some many other parts and leaving the rest? With such a late production date I'm going to do a lot more research before spending a few grand changing things "back" its very possible this is the way it left the plant back in 1970.
I'll take pics and post in a bit.
Oh and the seat belts? 26th week of 70 for the front, 27th week for the rear.
