<VV> Anothe X member question

[Paul]

Hi VV'ers,
I am rebuilding the front end of my Corvair powered dune buggy with 1964
Corvair front and rear suspension.  I noticed that several vendors list the
1964 front X member seperate from 65-69 X members.
I just got a NOS 65-69 X member and I can't see any difference from the 64 X
member. Does anyone know what the difference is, and can I transfer the
A-arms, etc, to the 65-69 X member?  Also, the vendors list all the bushings
60-69.
Thanks for your help,
Paul
