DOES NOT FIT 4X4 TRUCKS!!
Even though it says it is an exact fit for an ALL 1986 Chevy K20 trucks..it is not!! it only fits the 2wd model(and possibly big block) trucks.
The cable length of THIS cable is 25" if you have a 4WD model truck with a small block, it requires a 18" cable (that adanvce does not carry) due to the engine sitting closer to the firewall to make clearance for front axle.
Bottom Line No, I would not recommend to a friend
