I've found the small impact drivers that use the 1/4" hex drive
are great for dissasembling these old trucks. I've used my
Makita 18v for removeing stubbern screws and bolts from inner
doors and door hinges that conventional scrwdrivers or sockets
wouldn't budge. Works great on clutch head screws also.
Try one and you will be amazed at the difference.
