Speedometer Cables for FC Trucks
1 ton and
1-1/2 ton GM Step Vans, such as bread trucks and some Motorhomes, of the 70s -
mid 80s on GM chassis, are listed at Napa as a P-30 and yes, speedometer cables
are available in lengths to match your FC, first measure the length on your
FC-150 or FC-170, go with it to a Napa store and request a Speedometer cable of
that length for an 1981 GM Step Van P-30. My Napa is a main warehouse store and
they stock it, so if your store doesn't have it they can order it.
