Swap?
Suspension swaps are unnecessary
But make life really easy in addition to killing many birds with one stone.
When I built my first A body I used the factory K-member to put the 440 in place of the 340. I pulled all the front suspension, sandblasted prepped and painted every part.
In retrospect, this was a waste, 3 fold.... (and I'm sure I'm leaving things out)
1. I should have powdercoated
2. I still had the junk pre 73 biscuit mounts (and all the issues that come with them when doing the conversion)
3. It still handled like a 69 dart
Unless it was a low buck driver or non-restoration car, it's tough to pass up the function and beauty of an after market K-member.
