Rebuilding front and rear suspension
I am mostly concerned with body roll in corners as well as just having the front end not wander when I go over bumps. Hoping to be able to take it up in into the angeles national forest eventually. Drove the 110 from pasadena to DTLA today and man was that an interesting ride around the curves...
Good to know about the 73-76 front suspension
there's a lot of considerations. brakes, swaybars, rebuilding the components, each are their own system and each are or can be unique to years/production. for example, you can use any A-body lower control arm from 64~76. but, the 67~72 and 73~76 have their own unique swaybars that match their production years of control arms and corresponding k-frames, and the motor mounts are different as well. we're not going to talk about 64~66 sway bars and their LCA's because that won't work for what you've got.
however, the aftermarket is
rife with swaybars and there's
something that fits nearly any collection of parts-- yes, even arms that don't have the swaybar tabs.
so you can run the 69 K, an aftermarket swaybar, aftermarket or stock upper control arms with small bolt or large bolt discs.
there's lots of options, some are more expensive than others and there can be arguments that some are
better than others, but none of adding disc brakes and a swaybar is "wrong". the magic is in selecting the components that all work together, and that's why i always lean toward upgrading to the 73~76 stuff, it's a known entity that all works as a system and has a ton of parts availability and aftermarket support.
