Check the website at Wisners http://www.wisnersinc.com/additional_info/marlin_LARF_rifles.htm this link takes you to specific info for the Marlin 92. There may be more detailed drawings elsewhere on the site. They make new reproduction parts for many out of production guns, including yours.
if i find assembly/disassembly info for 1891 marlin 22lr/short will it be close enought to use for marlin 92 32 rimfire? i am amazed how hard it is to find! when i first got it from my dad i found full assembly/disassembly manual and put it on a disc but unfortunately it was destroyed in a fire!
