Coupe GT ???'s

[b1biker]

Can someone tell me what significant differences ther are between the 83 CGT
and an 84 coupe. What is the significance of the GT designation on these
cars. I have an 83CGT that was recently totaled and have just found an 84
Coupe, non-running of course, at an affordable price. Looking at swapping
many of the 83 driveline parts into the 84 body unless ther are good reasons
to repair the 84 versions. Any advice from the list will be greatly
appreciated.
TIA
