63 Dodge Dart, now let me see;)

:thankyou::thankyou::thankyou::thankyou:
Early-A's have the engine set farther forward by over an inch than the '67 & up generation, which is one reason they require their own headers.....I made My DC/MP 6-into-1 headers fit My '64 GT Cpe., but it wasn't pretty, basically I'll need to cut & re-tube some sections to make it 'right'. The other reason is the Early-A's front frame rails are ~2.5" closer together, so You lose ~1&1/4" per side for clearance. Steering box & pitman arm/tie-rods are full-into the later A header tubes. I am however, plotting to move Mine back about an inch, it will require a firewall mod behind the cyl. head, & tunnel mod at the starter unless I find the mini works better there.
I may employ the later bracket w/the thick early biscuit, but the K-member has a lot of room to slot/move the mount holes fore & aft. I should have at least 2 extra Early Dr. Side brackets, I'll check in the AM,....well, later AM,.....
