The screw (group 3.822) should be in any decent repair kit; the spring (group 3.823) is available.
The numbers are group numbers, not part numbers. Groups contain similiar parts from different units. The picture is from a Master parts book which covers several years. Once you find the group number from the picture, you look at the numeric list for that group and find your unit by application. There will be a 6 or 7 digit part number for the individual part.
