Re: [Chrysler300] Brakes / blue sky

Maybe not  true Ron . Been there. Had 58 D both ways , look up parts for 58 ,check numbers vs 59 or 57  you often got wrong one . Much of the literature in parts books all messed up about D . 59 has the later upper arms too , I think changed with brakes . You are right though all 59 are later stuff. Note two part numbers for upper arm bushings 58 . Late 58 , up , is Distinguished by increasing the thickness of the backing plate , bigger control arm bushings , I think front end adjusting methods changed too ( cams vs shims) ) backing plate thickness step  changed the wheel cylinder step  .   When you swap a  frame you learn all this the hard way . Not familiar with term “three platform “ at all . Maybe another change . But structural change was ( despite erratic  stories about when , or if all at once , or just 300 )  in 58 . 57 had problems , to put it mildly .  Noises failing to hold adjustments , locking if left sitting , etc not all  those fixed by upgrade either.     
Whatever , one D had the later parts factory . Other did not . I got so confused by this at the time , and — I am not being strident about it ... as ten years ago , — that I chased down a period Moog catalog , also even more confusing . Even corresponded with them by email . I won’t even go into ball joints , must be 4-5 of them in this period. But catalog gives you no dimensions , you find out when you get part . I vaguely remember Imperial used an upgraded ball joint sometimes listed as if fitting all 300’s . Sometimes the numbers are same size but mean different quality line , rubber etc . Very confusing . Finally took to 300F parts all fit ok. 
Do consider this as information from on the ground . And do not believe all you read on 300D front end orbrake parts. It depends. 
Main question was spindles , anyway . Sorry for digression. ..
