Early A K-member help

A buddy of mine went with a Magnum Force setup in his 64 Valiant. It is a tubular design.
Drawbacks:
WIDER turning radius.
Reduced suspension travel.
All of this because he wanted some header clearance....4 years ago and he is still running exhaust manifolds!View attachment 1715276468
I believe 60-66 A body K members are the same. 64-66 V-8 cars used the same K member as a slant 6,
the engine mounts are different. If I'm wrong, I'm sure someone will correct me. 67 up K members are wider
but suspension components are pretty much the same except for large and small ball joints in the components.
