Early a. Front end geometry. Any issues ?

Looking to replace front frame rails ( using 2×3 tubing) and possibly the K-member ( coil overs).
'62 Lancer. Frame rails definitely need to be replaced.

Should l jig off the original suspension pick up points, or are there any changes l should be aware of to help geometry ?

I'm thinking Ma Mopar pretty well did her homework designing things even in 1962 ( but before radial tires)

Any input is greatly appreciated.
