Anyone know of any newer cars who's interior, ie back seat and buckets will fit well in a first gen?

Buckets are easy enough to fit, more concerned about a back seat. And maybe a center consol.

Nightshade. Did you have any luck finding an option for your first gen. interior? I have a 66 2 dr. post with no seats and looking for something to put in that won't break the bank. any ideas? Thanks Barry.
