Hello, Good Morning! Joined after buying and, with your help, restoring a '64 Belvedere, but now looking at a '56 Plymouth Savoy 2 dr sedan 230 - 6, w/Powerflite auto trans. Have not purchased yet, would like to check out parts avail first. Seem to be having difficulty locating front 10" brake drums and front shocks (spring over) for this car. Are they avail? And does this car have u-joints or cv type on drive shaft. Every time I look up u-joints (anywhere), if anything comes up it's a cv joint repair kit. And other than a trans pan gasket that is avail, is there a 'filter kit' (does trans have a filter?) Any thoughts? Thanks!
