Avanti-X!

'63-'85 Avanti frame X-members are all interchangeable......True?

I'll say false as original frames were getting in short supply and reportedly 6 cylinder Lark frames were "beefed" up to be used in new Avantis.  Interesting that new Avantis were being built on 20++ year old frames that been sitting outside rusting all that time.  No wonder there were frame rot issues in the 80's Avantis before they went to the GM frames.

False is the correct answer here!....Although, with various modifications made to the X-member, it would fit 'across the board'..(That's what the Avanti factory basically did!)
