Could be a blown fuse.
The bed size is 6.5' of a dimension of 78x9x5 would fit a Chevy 1990 pickup.
The "heat maker" is broken. :(
It would be the 700R4
YES, They are the same engines. That would be a direct bolt in.
A 1977 Chevy pickup truck would have rotors in front and drums in the rear
That would be the 4L60E
Probably the steering gear.
No a 1972 Chevy pickup is not the same model as a 1973 Chevy pickup. I believe it goes from 1967-1972, 1973-1980, 1981-1987. Doors will work from 1973-1976, 1977-1987. You would need to find 1972 doors as they are the only ones taht will fit a 1972. 1967-1971 are the same but there is something different about 1972 doors.
Well known pickups are Ford, Chevy, Toyota, Nissan, and GMC. All of these companies offer a pickup suitable for towing a boat; find one that suits your budget and power needs.
Never seen one.
Left would be driver side.
that is a very hard question
