There are some nice looking parallel leaf spring cars around and then also just the opposite in that they get real clunky looking in the front, especially if it's a fenderless vehicle.

Now, my opinion, and with that said, don't back yourself into a corner, especially if this is your first ground up build. Even a traditional car will take some level of fabrication. A non-traditional build - well you can guess that that will entail LOTS more plus a level design skills. Something as simple as getting on the floor to do a bit of work on the underside, now becomes a PITA with that 'claptrap' hanging there.

OK - got that off my chest - some of the early Plymouth/Dodges (late '20s-early '30s) had an interesting looking front axle with a swoop in the center. Then there is the older Ford pickup for which you can find spindles and decent disc brake systems. Next would be the tried and proven Econoline front axles - also with decent brakes available. Anything non-Ford becomes problematical for parts

That rear end - I sure do like the coil overs on my '31 as it too unclutters access except I wish I had gone 4 link instead of 4-bar but if you are set on parallel leafs ...... just add a set of bars to prevent spring wind up.
