What's wrong with this picture Part 2, but much more serious this time.

frame on an austrlian mopar as standard does have zig zag section that bridges both sides of the rail from top to bottom and steel tube strengthening inside for the bolt hole.
it provides an ideal rust trap inside the rail so it rusts from the inside to the outside and cracks

total production from 1962 to 1982 of A body style vehicles for Australia and the rest of the Right hand drive world had them like this

and the method was used on US made Right hand drive export cars as well. the barracudas out of hamtramck for UK Aus SA west indies japan etc used the same steering box and mounting
it all seems to originate from the pre monocoque/unibody cars of the 40s and 50s.
the first right had drive valiants used a 5 tooth sector just like the ones used with the worm screw boxes.

however i agree its not the best design. but then again a 1 tab cantilevered steering idler mount on the K frame aint exactly sensible either :)

not welding or bolting the top of the upper arm mount to the lower section of the inner fender, the US doesn't Australia does with a stregthening plate and what ammounts to a wheel stud pressed through from the top or they did on the later cars

history gets its chance to prove one way or another what was good and what was less so.
