No they are not, The 78 does not have a computor. But the 88 does have and that means more wires and different wires.
NO it will not work. Everything is different. Cab mounts, body weith, ECt.
The 1984 700R4 will interchange with a 1988 700R4. The lock-up harness would have to be modified, changed or have a hydraulic lock-up kit installed. An easy fix would be to put the harness and swithes from the 1988 transmission into the 1984 transmission. The 1984 transmission is a weaker design but a working transmission will get you going.
Are the door interchangeable on an 1987 chevy truck and an chevy blazer 1988
Yes
No they were two different models. Sorry but the above answer is wrong. Those hoods are the same and will interchange. The body design change took place in 1988
Yes, But it won't look right. 1988 is when chevy redesigned the body / changed it.
NO. 1988 is when chevy changed everything.
remove the bed bolts and disconnect the wiring harness behind the bumper for the tail lights
Yes it will, samething
YES. Almost everything will interchange.
it can but you have to put a 4.3 wiring harness in and a 4.3 chip and you may have to get adapters for you transmission Correct, the 4.3 will not bolt to the 2.8 bellhousing.
Yes it will
