Lionel,
I must get back to re-loading the photographs.
I didn't do an apprenticeship but did work in engineering after going to Polytechnic in the UK. Mostly self taught from books, magazines and speaking to more experienced people (didn't have the internet way back then). Also learnt a lot by making mistakes.......
Wallit's gearbox was the first car one I've stripped & re-built, done lots of motorcycle gearboxes over the years though. Only did Wallit's gearbox because broken synchro springs were found in the bottom.
Lots of things other than the obvious to check for like wear on the synchro's, endfloat etc. etc. You need access to shims which sometimes come in a comprehensive overhaul kit then there's setting the pre-load on the bearings in the transfer box which requires more shims.
You can see why including labour it can quickly cost $2.5K and upwards for someone to rebuild the box for you.
The other option is fit it into your rolling chassis, test run it under load, listed for odd noises and if it seems OK fit it and move on to the next project.
