Sorry for you misfortune back then.
A similar story from my past.
Met a woman ( who became my daughter's mother ) with a 1963 Bus ..
trans was seized up , and the van was about 150 miles from where I lived.
I forget how I got it to my shop in Russian River area , Gurneville, Ca.
if anyone knows where that is ... a pretty triply place in under redwood
trees by the Russian River in northern Ca.
anyway ...I take the trans all apart ( this is about 1977 ) ...
bought all the syncro's and bearings and seals.
Then I cut the side out of another trans case, by hand with a drill and
hacksaw ....so I could set up the shifting forks in the trans I was
building.
Had things 'just right' ..but it just would not shift consistently on
the workbench ..
finally I decided it would shift fine when things were turning .
They did ....and we drove that Bus for quite a while with a fine
working transaxle.
Sold it to a guy a couple years later ..
he managed to wrap it around a tree sideways. Just can not imagine how
he did that. I don't think I could do that driving blindfolded, be he
did somehow.
But that trans was fine the whole time..
I probably spend under $ 125 on parts .
maybe much less than that even.
Them's was the days !
