ya drove 5 miles and ya got all those questions?? a serious road trip road trip oughta REALLY get ya confused.
ok--lessee if i can remember them all.
napa sells replacemet cables, including fancy knobs in different colors.
that ain't a line lock, but works close to the same. it's a mico lock. sorta like a parking brake. ya mash down on the brake, and engage the lock. it keeps the brakes locked while letting the brake lights go out. good for TEMPORARY parking, or holding the truck in place. they will, in time, bleed off.
the starter. well--better yank it and see if there's any teeth left on the flywheel. pretty good sized UHH-OH! yaknow, you can buy a replacement bendix for the starter. ya did know that, right? cheap fix!
yeah ya shift the 2 speed with the knob on the dash.
timing advanced too much can cause the overheat, but i sure would be looking to see if there is water circulating in the radiator.
looks like and easy restore.
red and green hood?
congrats on the new hauler. it looks pretty decent, and if sha'a a runner, then ya got a workhorse.
good on ya!
