Hi, I posted in the discussion area too regarding this, but figured being parts related Here seemed a good place also. Im in search of some parts to get my Old D4 4G going again. Mostly I need a ring gear ( pn 3B-7307), the rear gear cover on the pup engine (Pn 4B 640), folding locks ( pn 2A 3662), and the rear bearing housing/ brake drum assembly for the starter pinion (pn 3B 6399). Any Help is much appreciated, thank you.
