R7ME gearbox rebuild - looking for tips, manual pages, or wisdom

Hi everyone,​I’m about to tackle a full rebuild on my 1999 Suzuki Jimny’s manual gearbox due to a failed input shaft bearing.
 All of the information, teardown guides, and videos online cover the later R72 box, leaving the R7ME a bit in the shadows.​Since information is scarce, I would highly appreciate any advice from anyone who has successfully rebuilt one of these.​Are there any specific "gotchas" when splitting the main casing or removing the 5th gear assembly? Any hidden snap rings or detent balls that like to fly across the workshop?
Specific order for bearings removal/install?
 ​Does anyone have copies or screenshots of the specific R7ME transmission overhaul pages from the early SN413 service manual?
 ​Any tribal knowledge or tips before I crack this case open would be massive.
 ​Thanks in advance!
