the gear shift linkage occasionally jams up.
I was on highway 7 in Perth in 1991, at about 11pm on a Saturday night heading west home to visit parents ,working in Ottawa thru a uni summer break after I got off work late.
Moved the shift lever to put in gear, and hear a bang then it spun around. Linkage part broke.
Crawled under truck, saw the problem, saw broken end was on bottom so dangling link would not be a problem.
Find logs to stop back tire, tool box and seat moved up to jam clutch pedal to the floor.
Crawled back under and shifted on tranny levers into second, using pliers.
Revved the engine and rode the clutch to start moving from second gear. Drove 300km home in second gear. Would coast down hills with clutch to the floor to let engine cool a bit.
Windows down and heater going full blast to help cool the engine. One stop in Peterborough at late night gas station to buy more gas, since eating more with higher revs. Home 3am.
Next day down the shop my dad managed, pull a short rod of 3/8" mild steel cold rolled round bar, bend the 90's it needed after heat in the oxy torch. Use broken part as a template
Grind the bent ends to length, drill holes to accommodate cotter pins, and install it. Ordered a factory replacement part but never end up installing it. The home brew worked until the ignition module died in 1995. Brake lines were also starting to fail here and there and it became too much of a pita for an everyday vehicle and I had the truck towed to a scrap yard Second engine but over 450k on the rest of the running gear which was pretty good for a 1977 vehicle.
