Hoy hoy screaminchicken! I guess the question should be, are you going to do a rolling resto? That's how I'm doin' my two. That way you can have fun drivin' it while repairs are underway. I don't care what it looks like, to a degree.
Of course one day they will have an extended stay off the road. That can be due to several factors... time, funds and parts. Other things get in the way like work and family matters.
From your pics, it looks like you have quite a hand full. But don't let that scare ya off. One of the thing you should get your hands on is the documentation on your 'bird. Pontiac Historical Service is where to get that: http://www.phs-online.com/order.htm Looks like you have some nice options.
I'm curious of your build date and option package. I'm sure the bench seat is from a '67 'bird. In '68 and '69 the Deluxe interior was the only way you could get a bench seat. Some have experienced cross over year changes that aren't documented.
